Rope Spokes And Sam Hill's New EWS Winning Tyres | GMBN Tech Show Ep.30

– Welcome back to another weekly GMBN Tech Show Coming up on this weeks show, we take a look at some rope spokes, some custom painted bikes, we have a brand new uploader for all of you guys and girls to enter all our Bike Caves and Top Mods and stuff, and of course, we have loads of that stuff that you’ve all sent in already Okay, so first up on tech news is rope spokes, who’d have thought it? So, Pi Rope spokes are actually made from Vectran, which is a fiber type material, and they’re braided, so it’s kind of a weird concept, and hear me out on this, because I know some of you will be thinking, “god, how’s that gonna work, because spokes have to be “made of steel or aluminum, or carbon”, something like that Now spokes actually don’t rely on compression forces that much, they’re more reliant on the tension, so therefore you can use other things, and as you might have seen in my old bodges video that I did, I actually repaired a broken spoke using cable ties, and it’s obviously not gonna add that much tension to the wheel, but it was enough that the wheel didn’t buzz on the frame, to get through the frame, enough to get home, basically, that’s the concept Now, this company, Pirope, look on screen now, they make this hi-tech fiber Vectran, and it’s five times lower density compared to steel, so they’re super light, but they’re also incredibly, the tensile strength on them is incredibly strong, it’s a braided construction, and because it’s basically a braided rope, as opposed to like a solid structure, in theory they should never, ever snap, I think this is a really, really interesting concept, and I really wanna try this, because I love to lace up a set of wheels basically using this stuff and try it for myself, ’cause I think it would work really well I mean, there might be weight limits, and stuff like that, it might only be applicable for cross-country riders, or perhaps road cyclists, but I think this is one of the coolest and strangest bits of tech I’ve seen for some time These Pi Rope spokes I think could be a really good bit of future tech What do you guys think, is it mental to have spokes made of rope? Let us know in those comments Now next up is just something I spotted on Sam Hill’s bike, obviously I wasn’t at the most recent EWS where he won, but, he’s actually running Michelin DH 22 tires on his bike, so obviously Maxxis are huge in the world of tires, so are Continental, all the other brands, but Michelin, actually were huge in the 90’s, in the downhill scene, all the way up to sort of the early 2000’s They kinda sloped off a bit, they’ve always been there, always made some really good tires, but I actually have a feeling that they’re gonna make a massive comeback Now they’re obviously doing and they’re proving very well in the Enduro World Series, so if you have a look on the screen now, you’ll see Sam with his bike there, and you can see very clearly the Michelin branding on the tire Now, back in the day, the tires that were famous were the comp 16 and the comp 22’s, which were later called the DH 16 and DH 22’s The rubber compound was phenomenal, at the time, not many people were doing soft or sticky, or even slow rebound rubber compounds at the time, and then Michelin hooked up like almost nothing else, they were a little bit slow, and the casing was a little bit heavy, but I think this new DH 22 is actually gonna be a bit lighter but a better casing on it, of course it’s gonna make the most of the new tech you get in tires now, whereas instead of just having a soft compound where those side nobbles can deform, they tend to have a harder compound base to give the tire a bit of structure, with soft compound rubber over the top for the traction, so there’s gonna have a lot of that stuff in it, and I can’t imagine saying they’re running a tire that’s gonna be that heavy or that slow because of the fact that A, he’s winning races with them, and B, he’s gotta pedal’em with flat pedals, so he needs it to be as efficient as possible, as well as gripping He’s got prototype tire inserts made by Nukeproof, and I’ve spoken to Nukeproof, and I’m actually gonna be getting my hands on some of these soon to have a look at, so we’ll get those on the tech show as soon as possible, ’cause obviously tire inserts are big news, you know they’re actually one of the best ways to stop flats during a race these days He runs his handlebars at 750 millimeters, and interestingly, because he used to run volume spacers in his forks and shock, he’s not running any volume spacers front or rear, so I actually find it quite a strange setup but it’s clearly doing it’s thing because he rips So since last weeks show, where I talked about the Sick bicycle Sleipnir, which is of course, their concept bike at this stage, Jordan from Sick actually dropped me a line, with this picture, it’s a rendering of it, I think you’ll agree it looks pretty special Now he just wanted me to know a few facts about this before they go into production, I think this is pretty interesting, so it’s 180 mil travel, front and rear, that’s what it’s optimized for, rolls on 29 inch wheels, obviously I’m a huge fan of 29s anyway, so I really like that, and if it’s designed for racing and tackling rough terrain, then a bigger wheel, in a lot of situations, can be faster and better controlled, so I think that’s a good choice He wants to point out the fact it’s completely silent, because it has no derailleur, no chain guides, no chain slap, no losing a chain, like, ever, this system with this bike, very simple, a high pivot basically with an idler roller, connecting to a pinion gear box Now, the gear box, of course gives you centralized mass on the bike,

puts the weight all low down on the center part of the chassis, so your unsprung weight ratio’s really good, so obviously the front end of the bike’s nice and light, and it’s taking the weight you get with a big cassette and chain and everything off the back of the bike, and putting on to the middle, so your suspension, just like on eBikes and other sort of heavy duty bikes, like the Orange we checked out at Eurobike with those plates that bolt on to add weight to the main frame, it’s just like a really, really good setup Now, they wanted to build the bike to make it future-proof, so there’s a few things, so there’s no weird standards on it, so it’s a ZS tapered headset, 31.6 dropper post it takes in there, and interestingly, it takes a 142 single speed hub at the back, not a 148 boost, because on a 142 single speed hub, the flanges are way further apart anyway which is one of the goals of 148, so they don’t actually need it to go that wide There’s post mount disc, off the shelf bearings and fixtures so if you ruin your bearings, you knacker them, you can get them in any sort of hardware type of store Replaceable dropouts as well, and one of the cool things about the replaceable dropouts does mean that there’s something else coming, I’ll tell you in a sec, open source parts on there, ’cause they want people to be able to sort of like, use this platform Now what if the Pinion gearbox goes obsolete before the frame does? Well, firstly, I don’t think that’s gonna happen, I think Pinion are just getting warmed up, and I think they’re gonna keep a standard there with a footprint with how that mounts onto a bike, now it’s quite cool that they’re actually, they’ve got a plan B for this, and it’s to generate a cradle that can accept a BB73, and there’ll be other cradles as well, to accept other future parts, basically, and the idea is, in combination with the replaceable dropouts, you could, if you needed to, put a rear derailleur on it and a regular bottom bracket, so I think that’s a pretty flippin’ interesting bike, and of course it’s got that wild, really progressive geometry, really long front center, probably got quite a long chain stay on it, slight head angle, steep seat angle for climbing Looks pretty good to me, what do you think? Okay, so this really isn’t tech news as such, but custom paint jobs, you gotta love them, and Fatcreations, which is done by Ali McLean, they’ve gotta be one of the best companies out there, so check this out, this is a pivot on screen, and I think this is one of the most mind-blowingly beautiful paint finishes I’ve ever seen There’s several shots of it there, and it’s just unreal Now in case you didn’t know, some of the bikes Ali paints at Fatcreations, he obviously does his business with his wife, I think she does all the detailing with the graphics and stuff, but some of those bikes have 200 hours worth of work on them, so of course it’s not cheap, but genuinely, I’ve seen probably 20 or 30 of his bikes, and I’ve never seen a custom painted bike with a finish that good, I think it’s like, hands-down the best I’ve ever seen Of course they’re very expensive, but they’re very bespoke I urge you to have a look on his Instagram, give him a follow if you haven’t already, it’s @Fatcreations, it’s on the screen now, just with a few other bikes and stuff, ’cause he’s done so much cool stuff, and I think it’s really inspirational, so check out Fatcreations, wicked company And the last bit in tech news is actually a bit of computer tech, and it’s something I’m super excited about, is we have a brand new uploader service, so you no longer have to, like, tag us and stuff, or email us, and we don’t have to filter through all those different email accounts to find stuff, you guys can simply click on our upload page, the link is on the screen at the moment, and it’s also in the description below this video, you simply click what submission category it is, so for example I’m gonna click here for Bike Cave, then I’m gonna put my kick-ass Bike Cave entry, tell us a bit about where you are, what your name is, all that sort of stuff, click on the links, make sure you go to the terms and conditions, just so you know, it basically just says that you’re giving us authorization to put your really cool Bike Caves, Rewinds, all that stuff, on this show, and then you can click to upload your photos, I’ve just gotta find my cool photo that’s on my desktop, that I’ve got ready, okay so there’s the picture of my Bike Cave that I’m gonna submit into Bike Cave, click on the link, and in it goes Then, simple as that, click upload, and you get a little message pop up on your screen that says “look out for your Bike Cave on the channel” It takes the hard work out of writing an email, makes it a super easy system for you guys to enter, so let’s get cracking, get your Top Mods entries in, get your rewind entries in, anything retro, whatever there is, send it in, and send in your Bike Caves, we love them, and next week I’m hoping that you guys are gonna inundate us with all of those entries, and we can pick straight from the new system, and put’em straight into the show, so get cracking, get them in Okay, so straight into Bike Cave now, Bike Cave, of course, is where you keep your bikes, where you work on your bikes, where you tuck them up at night, all that sort of stuff, could be the back of a caravan, could be under the stairs, could be anywhere, wherever it is, send your Bike Cave in,

don’t forget we’ve got that new uploader now, so there’s a link to it on the screen and there’s a link in the description below this video, it’s nice and easy, and it means it’ll go straight into the box, that makes me put it straight on the show, so get your entries in So, first up we’ve got one from Mason Martinsons here, “Hi Doddy, I’ve been loving the GMBN Tech channel, “especially the Bike Caves, so I thought “I’d try and get my own onto the show “My bikes are stored mostly in the garage “on hooks on the ceiling, “Bike Caves a shed in the back garden, “My mum said I could have it, I’m 14 years old, “The bikes I have are my Cannondale Jekyll,” very nice, “My Haro Extreme X6, my first proper mountain bike, “my Ironhorse bike, just a hardtail for getting around, “a freestyle BMX, and a BMX race bike “Thanks for making the great content, “and check out my bike shed.” Tell you what Mason, you’re doing pretty alright here, you’ve got some trick stuff in there I like your skateboards hanging up there, you’ve got a pretty flippin’ good sound system in there as well, couple of floor standers, I’m not sure what they are, they could be Mission or maybe Celestion speakers, and a subwoofer as well by the looks of it, and there’s stuff to do with bikes and bike case, but must sound good in there, also like your rack on the wall for holding the bike, that’s really cool as well, that’s a good setup, your bench is looking good, your pegboard’s looking good, Harley-Davidson badge on the tool chest there, nice setup, I like it, I think it’s a smashing little setup you’ve got there, dude Wicked, so thanks for sending that one in Mason Okay, so next up is from Dan Scotney, “Doddy, here’s some bike art “I recently made out of some recycled bike parts, “the pictures you showed last week with the bike frame “light and shot lamps were really inspiring”, yeah they’re really cool, and actually if you look on Pinterest as well, there’s quite a lot of other bike art related stuff on there, I think I did a page on it a long time ago, might give you some more inspiration to make your own stuff, “As you can see in the pictures, “there are coffee and tea coasters”, nice, yeah, “A wall clock, and a custom made Bike Cave sign”, oh yes, I think we need one of those for in here, what do you reckon, should we have our own Bike Cave sign? I reckon, let’s get one made, in fact, if anyone wants to make one, or if you wanna make one, or any bike art for that matter, send it in, and if it’s cool, we’ll get it up on the walls in our studio here In the meantime, let’s have a look at the rest of your pictures, Dan, I tell you what, I really like the clock, nice and simple, great use of an old cassette there, I’ve got a few of those hanging around, I could probably knock something up myself So I guess you just got a clock mechanism, taken it out of an old clock and boshed it straight in there, bish bash bosh, nicely done, very nice Yeah the coasters a good idea, actually, although I would be worried, I have to say, you’d scratch the glass on that table, but at least it looks cool, that’s more important isn’t it? And a good mug too, nice touch Next up is from Scott, “Hi Doddy, loving the show, keep up the good work”, thank you Scott, it’s always appreciated, but genuinely, it wouldn’t work without you guys sending in all this great content, so if you guys keep doing that, it makes the show great, so please carry on “Sadly, my wife wouldn’t let me have a Bike Cave,” boo, “so I’m lumbered with a bike box, “which just about fits my bikes, tools, “and foldaway bike stand, watching the show has been “an inspiration to me, as I suffer from multiple sclerosis, “and it encourages me to get out and remain as fit as I can, “haven’t been riding in three weeks as I fell of my bike “and broke my elbow in three places”, oh, dude, that’s not good, “So I’m feeling sorry for myself, “having a mention would cheer me up.” Well I’ll tell you what Scott, it’s not all bad, because when you said it was a bike box, I thought it was gonna be really bad, but actually it’s basically just like a small shed, I think that’s great, that’s not bad at all I like your little furnace outside, Boardman’s looking great Is that George Clooney? What’s the story with George Clooney hanging up? Is it like, you throw darts at him or something? I dunno, very odd, but it does look a good size, I can see your work stand in there, I think that’s pretty cool actually Yeah, nothing else to say, I think that’s actually a pretty good use of space I reckon you could slowly extend it though, without your wife knowing or noticing too much, until it’s magically like the size of a shed, I reckon you could do that bit by bit Scott, I think one of the coolest things is that despite suffering from multiple sclerosis, you’re still a mountain biker, and definitely a toughened one if you’re out there busting your elbow, so let’s hope your elbow heals up fast, don’t ride on it too soon, ’cause they’re pretty nasty, want it to heal properly so you can get out there and shred, but nice work Scott, thanks for sending that entry in, and try and turn it into a shed without your wife knowing Okay, so on Friday, in the Dirt Shed Show, I was chatting to the guys, especially Martin, about Camelbaks, because, really, it’s been so hot recently that we can’t physically carry enough water with us all the time, so, and this is how the story goes, Camelbaks now, there’s loads of different styles out there, and I think it’s a really cool product, because it’s kinda like a hoover, and I touched on this in the Dirt Shed Show that it’s such an established brand name that, even though Camelbak is the brand and the product is a hydration pack, or a hydration bladder, you tend to use the word Camelbak, “where’s your Camelbak?”, it might be a different brand, but it’s still a Camelbak, so they’ve kinda done what, they’ve done a hoover, really, and I think it’s amazing, but did you know the story about where they came from?

I think this is really cool, so there was a medic, this is way back in like the mid 80’s probably at this point, called Michael Eidson, and he’s also really into his triathlons, now he was entering a race called the HotterN’ Hell, and he was worried he couldn’t carry enough water, and he knew just how important it was to keep hydrated, especially doing that sort of race where you’re exposed to the sun, you’re in the saddle for such a long time, doing stuff, so he got an IV bag, which you or I would probably know as a drip bag from hospital with the tube, slung it in a tube sock, bulldog clipped it to the back of his jersey, and stuck it in the rearward pocket there, had the hose hanging over his shoulder and although he got some funny looks from other cyclists, who were struggling to use their water bottles, he completed the race and stayed hydrated the whole time, and then the concept for the Camelbak was born, and I think you’ll agree it was a brilliant idea, because at the time bikes were fairly heavy, and loading them up with loads of water wasn’t ideal, and, of course, being bikes without suspension in those days, water bottles were prone to firing out, so actually keeping hold of your water can be quite tricky, and could be quite tricky, and this is what the very first Camelbak would’ve looked like, this is a remake just to celebrate them, so it’s been around since 1989, trading as Camelbak, and I actually had one of the very original ones of these, it didn’t have this graphic on, it had a little purple patch with a neon orange writing on it, it was literally a neon sleeve with really, really puny little strap system, and a bladder inside, as simple as you get Of course, this bladder is like a modern day bladder, so it’s a little bit better than the original that was in there, but the whole principle was the same, stick it on your back, hose goes over your shoulder, drink while you’re riding I think it’s an absolutely brilliant system, and I love the fact there’s so much variety in them now, you get the ones that sit up high, you get the lumbar packs that are down low, even the bumbags or, as some of you might know them as fanny packs So there’s a lot of different options out there, and I think it’s just one of the coolest products that’s ever been in mountain biking So if you look on screen now, here’s a few of the original Camelbak adverts, in fact this one with the spacesuit on screen you see now, it’s a little bit more, it’s a little newer, by comparison, but if you look at the bottom, there’s the halfpack, and there’s the Camelbak, in fact, the color of the halfpak is exactly what my original Camelbak looked like, and then some of the other adverts, you can just see, it’s so old school, “Camelbak is the best drinking system ever made, “It’s user-friendly, and super lightweight, “your answer to thirst”, and you know they actually had a moniker back then that said “hydrate or die”, which would, basically became the company slogan, and it’s actually true, and it’s just really quite cool, “hydrate or die”, Camelbak, there you go I think what they’ve done is brilliant, over the years, and, like I say, you know, they’ve done a thing, they’ve created a Camelbak, created a hoover. Pretty cool Okay, so now it’s time for Top Mods, and we’ve actually had so many in, but I couldn’t decide which ones I want, so actually I’m just gonna put a single one in this week, and we’re gonna have a bit of a heavy session on those next week Now the one I’ve decided to put in, I think, this is a bit of genius, so on most multi tools, you’ll find there’s probably a tool that you don’t use that much, so in particular, the one thing I’m gonna show on the screen any second now, is the multi tool with, you normally have a little tire lever on there, which of course, as you know, on a multi tool, doesn’t really do a lot, it can be used in certain situations, or you could bend it off, you could strip your multi tool down, just like my friend Finn has, so Finn works at TF Tuned shox, and he put a house key on there instead, so check this picture out I think that is one of the coolest hacks, and one of the most useful hacks I’ve seen, so he keeps that on his bike all the time, so he’s always got his house key with his bike, I think that’s genius, because you can really minimize on the kit, and you don’t wanna be carrying keys in your pocket, if you can help it, anyway for obvious reasons So I think this is a great hack, I’m actually gonna do this myself to one of my multi tools because I don’t use that little tire lever thing either, I can generally get my tires off with my hands, and I do carry a separate tire lever by Topeak, so that’s all good, and I think that is one of the best hacks I’ve ever seen, so as well as Top Mods, if you guys have got any really creative hacks like this, I would love to see them, I think that is a bit of genius, what do you guys think? So, tech of the week time, now, and one of the coolest things I saw at Eurobike was the brand new DT Swiss F535 fork, and look what I magically have here, in my hands, got one here to have a little go on, and get to know it a bit on the inside, ’cause it’s got position sensitive damping, which of course, I’m really interested to see how that feels out on the trail, just a quick version of position sensitive damping, it basically means in this case, that there’s almost no damping for the first sort of portion of the travel, so I think that adds up to about a third of the travel, so it’s incredibly supple and active, but then as soon as you get high velocity impact of any kind, the damping kicks in, so I think this can be an amazing fork,

but, there’s a few little cool things I just wanna pick up on So, as you can see, the top of it, concealed, there’s no dials or anything, and the same on the bottom, it’s all tucked away, very neat and very stealthy looking You actually take out the end of the axle, and within that, there is a tiny little torx key here, now that is used to access under these caps, just gonna undo this one here, even the caps themselves are really cool, ’cause they have a captive bolt, which means you can’t lose the bolt that holds it together, there’s a rubber seal that runs around it, and it says “compression right side”, because the caps look the same, but obviously they’re not gonna fit on the wrong side, so just a really nice bit of detailing there to make sure you get it right Now this particular one is set up for a remote lockout, so I’m gonna give this a little go on my scot, just to see how the bike feels, basically, with this fork on there, and this is compatible with the remote lockout that’s already on there, and it’s got real cool stealthy cable roots, and it goes out the back of the fork, so instead of having the dial on the top like you see on the fox forks, it’s really concealed and out the way, I think that’s really, really cool, but most importantly with this fork is the fact that you’re covering up all these dials which of course, on normal bikes, you get the dials for easy access to them, I think the reason that it’s so cool on this bike that you cover them up is the system for setting the fork up in the first place Now DT have a system for adjusting the sag using an app on your phone, so I’m gonna show you that once I’ve downloaded that and I’ve fitted the fork to my bike, but you set it up with accurate weight settings and that, and it tells you exactly the settings you should have for you, and apparently, once you set it up, you never need to adjust anything, pure stealthiness, basically, and there’s another couple of cool things I just wanna show you, I got an integrated mudguard, so very similar to the Syncros mudguard, in fact, that I’ve got on my Scott, on the fox fork that came on there, very nice, it plugs in the back of the fork arch there, it’s got bolts to hold it in place, it covers up the little waffle pattern where the mud would get in there, and it stands out the front, it’s really neat, just an integrated option, I really like that, and also, there’s something else that’s really cool The cable routing here for securing the cable to the fork brace itself, on most bikes, you have a little plastic clip that goes over the hose, and you have like a three, three and half mil bolt that goes into the fork Now it’s very easy to strip the threads accidentally on that bolt, so what DT have done is they’ve got a root all the way through, the bolt goes in from the back, so, of course, it’s replaceable, there’s a little clip which is made of plastic, to hold the hose, when you tighten the bolt from the back, it clamps down on the hose to hold it in place, and it comes with a spare one as well, so really cool thinking from DT Swiss there, love what they’re doing, and I can’t wait to just have a feel of this, to see how it is, what I can show you, just out the box, look how supple that is, just moving out my hands against the stanchions, you can see how well that moves, and that’s because internally, on the air spring, it actually has a coil spring that’s activated for the first 8 millimeters of the travel there, before the air breaks in, and apparently it’s completely seamless in feel, you can’t tell when it goes from the coil to the air, so, very cool bit of tech there Okay, so next up, it’s time for Bike Build, I’m just gonna zip upstairs to the workshop, so I’ll see you in a minute Okay, so welcome back to Bike Build, of course, the bike’s coming along quite nicely, I had an issue, because the particular chain ring combination that came on this DMR axe crankset, is not compatible with this frame, and it’s actually too big as well, it’s a 34 tooth, now Praxis very kindly sent me one of their waverings, but that was also a 34, and it’s a bit like “gah”, I didn’t realize, actually until I went to fit it, so, thankfully, Olly Wilkins and the DMR crew sent me one of the DMR rings, so this is called The Blade, and this is a 32, and this looks bangin’, this is really nice, narrow-wide profile on there, it’s a direct mount, so I’m gonna take this existing Praxis chainring and spider off the crank, direct mount that, stick the crank on there and we’re gonna get real derailleur on it, and we’re gonna look at the chain, ’cause I got a pretty cool chain to go on here too So, as you can see, the interface on the back of the crank there is ready to accept that new chainring straight on, if you were doing this on a chainset that’s already been used, for example, you’ll wanna give it a good clean, but this is brand new, so it’s a fairly simple process, I just need to locate the correct holes there, and then just slide it into place, now even though this has just been taken apart and it’s all in good nick, I’m still gonna put some thread lock onto those bolts, because they can be a pain, and they can be a source of creaking, which of course, we all know, creaking can drive you crazy on a bike, so we don’t want this bike to creak Right, so the chainring is in place, I think you’ll all agree that looks pretty sweet, nice and slender, the 32, of course, on my personal bike,

I run with 12 speed on the back, I run a 34, ’cause I can get away with the bigger chainring, and it suits where I ride, gone for the 32 on here ’cause not only is it a bit more compact, a bit more lowered down and stuff like that, it’s got the cassette on the back with a 9 tooth on the back, so of course 12 speeds tend to have a 10-50 spread, this one starts, little baby 9 tooth, so it’s gonna give it a pretty good gearing, I think, so just time to put a little bit of grease on this axle, and then slide it into the bike Okay, so, get this box of components back out, won’t be needing that, and then a five mil Allen key, and let’s get this into place here Okay, we’ve got our derailleur on, that’s got a strong clutch on that, you’re not gonna drop a chain with that bad boy So, as always, when you’re fitting a derailleur to a bicycle, the first thing you wanna do once you’ve secured the main hanger bolt, is get your upper and lower limit screws sorted out, so they’re the two screws at the back of the derailleur, in this case, it’s an Allan bolt, actually, which is quite a nice novelty because you tend to have to use a Phillips or a flat-head screwdriver to do that, and basically you wanna make sure that when you adjust the higher one, the upper guide wheel is completely underneath the smallest sprocket, and then the same with the bigger one under the bigger one, so in this case it’s this one for here, I can just about see under there, there we go, so my upper and lower limit screws are done already So, for a chain, I have opted for, and I’ve been really superficial about this, ’cause it looks great, black and gold Connex, 11 speed, so out comes the chain, it’s got it’s own dedicated master links inside, now when you’re speccing a chain for a bike, they obviously, they come in a single length, and you’re gonna need to adjust the length using a chain tool or a set of chain pliers, now, what you need to take into account with any chain link on a bike is some bicycle designs you’re gonna get some chain growth as the suspension compresses, so what you wanna be doing on a full suspension bike is release the air from the shock, so you can cycle the wheel through it’s travel, then you wanna get the chain, line it up around your system, and then using a third hand, this is the way I recommend do it, gradually pull the chain in and hold it using that third hand, cycle the back end through it’s travel, and you wanna make sure the derailleur stretches when it’s at the absolute limit, but not crazy, don’t wanna have an acute angle like that, because it’s putting too much strain on it, and you can actually snap the derailleur, in the event of a big compression Okay, so this is a little bit of a bodge just for demonstration, I’m manually holding the derailleur in the biggest gear there, and I’ve just got my knee holding back end, almost all the way through the travel there, just to accentuate the point of what you’re looking at, so in this particular case, it’s actually not far off, so I would actually split the chain, I would take out two links there, and I would take out one here, basically, and then I would join it together, just gonna let the rear wheel travel back down again, just so you can see the effect there, you see it slackens it right off there, so the idea is you wanna see the chain at the most stretched it can be, then you pick your correct chain length, other than that, you join your chain, and you’re good to go Okay, so they’re just a few of the factors you need to take into account, in an ideal world, you wanna make sure you do your cable routine, I don’t wanna do that live on camera just because I’d have to faff around getting the internal cable in through, so I manually held the derailleur in position, but you get the idea of using a third hand, so this particular one I’ve made out of an old spoke, which I just cut down and bent the ends round, just a really valuable tool to have in your collection, especially for trail side, if you manage to break a chain, and of course, let the air out of your rear shock, cycle the bike through it’s motions basically and see where the chain is at it’s longest, give it enough slack at that point so it doesn’t strain the derailleur itself, and then you’ve got your good chain length So, what I’m gonna do now in between now and next weeks show, is get the rest of the gears in place, get those brakes on, get it basically set up, ’cause we’re nearly there now, and then we’re gonna look at a few cool finishing things, including some suspension tweakage Okay, and the last thing I just wanna talk to you about before we disappear for this weeks show is if you like our gear, if you like our clothing, you might wanna head over to our store now, ’cause we’ve got a summer sale on at the moment, if you have a look on screen, you can see some of the really cool stuff you can get, it’s up to 50% off, and of course, the sale is on until Monday the Sixth of August, so you’ve got a little bit of time there, not that long left now, so get on there, get yourself some bargains, we’d love to see some shots of you guys repping our gear as well, ’cause it’s new t-shirts like the one I’m wearing, there’s the cool mugs, anything you’ve got, any GMBN gear, hashtag, get some pictures and get some hashtags going, and share’em, let’s see’em, let’s see what you wear, what you like
