Welcome. To the gcn, tech show this, week we have new world tour bike sponsors, broken. Time trial records a crack set that will make you faster and a, scientific. Breakdown on. Why era bikes are faster. What's. Hot in the world of tech this week well, we may be in the midst of Tour de France fever but. In, just six weeks time we'll be lining, up for the first races, of the cyclocross, season, well I won't. But others, will read admission is headlining, its potential, as a cyclocross, bike that it really is an all-round. Multi-purpose. Cycling. Weapon. And it's. Been you know really well thought out with all the latest industry standards, and this, you, know very future, proof because of it yeah, and they're releasing it in carbon and aluminium with, the carbon version weighing just eight hundred and eighty five grams which is pretty good for a multifunctional. Biking the, aluminium version, not, so light 1600. Grams for that one the frame next, up is this ingenious, new, device, from hex locks now you may be familiar with hex locks because of their special, security, system, on Allen bolts and it means that any allen bolt on your bike can, only be unlocked with. A unique key they. Are a really cool designer and I didn't really know anything about them until today however, they've, not released the multi, fit through, axle now, you may be wondering why, do we, need a multi fit through axle well this. Is one through axle to rule them all now anyone that's ever had to replace a through axle on their bike will know what, a pain it can be there. Are roughly 30 plus different sizes, and shapes of through axle meaning that it's impossible for most bike shops to stop them also if, you need to replace one in a hurry you can be well literally, screwed. By. Me I never knew there are so many different standards how do their. Manifest apologies isn't it it's absolutely mad Chris, would, you like to pedal further and accelerate, faster, than ever before, absolutely. Ollie who wouldn't well it, sounds like you need this this, is the mg Tek chain, set or the mg Tek old team chains that's it I should say yes which the makers acclaiming will do just that now the product, is currently, on Kickstarter. And it, uses a multiplication. Gearing. Mechanism which. Apparently, can double, the leverage offered by a traditional chain. Set design, inside. The mechanism are, additional, cogs or planetary. Gears and these, are actually able to spin, the chainrings, 1.4. Four times faster than. The pedals, sign. Me up on it it sounds like I really need one of these they'll be interesting to see if it really does work well. Perhaps. They'll be a spinoff, yeah. Well. Either way you, know respective, of the marketing, claims there. Is a, potential. Advantage, hearing that it does allow you to have a much bigger gap between the. Two chainrings, so, despite. Keeping the chainring small they're only I think 37, and 25, on this particular setup. They've got in the video but the. Effective gap between the two chainrings is 21. Teeth so you have a much bigger gear range because of the additional cogs and things else almost, twice the normal gear difference, yeah we must without having a big step between the TSA potentially, if they use their have, you interesting this week has also seen the news that BMC. Is set to replace Civello as the bike sponsor, for Team Dimension, Data we. Do think Sabella we are going to stay in the world tour team though if they take over the bikes wants a shift from giant Sun web where. Does that leave giant well, it looks like they're going to be taking over from, BMC, with. The new team CCC. As, they enter the world tour next year yeah just. To be clear that mean that's the BMC team management so it's not going to be called. The BMC team it's not gonna be giant BMC yeah but, I'm just a little bit disappointed, that they're not going to be called yeah BMC. CCC. So, many C's yeah don't. Mind.
This. Week we are asking what is the effect of bite tech on the results, of the Tour de France and to do this we've, done some statistical. Analysis, we have indeed of the stages, so far nine, have been won on era bikes and six have been one on disparate bikes the. Victories on the disparate is coming courtesy of Segen and give area with their special adventures, and John. They can call on his tractor month yeah, an interestingly no. Mountain. Stage your uphill finish, has, been one on this brakes have all been on rim, brakes and some, riders are exclusively. Choosing, to ride this brake stitches, again while other, riders are exclusively, riding, just rim breaks such, as ala Filipe yeah, but we should also perhaps point out that although no, uphill finish or or mountain, top stage has been won on a disparate bike it's, also being joy this year the talk which is a first thought I can remember so. Perhaps if it was to rain you would see riders opting to choose disks for the more dependable. And predictable, braking on carbon rooms yeah it would be interesting to see so. On they talk is through the options and choices that the riders have available to it so, in terms of bikes science. And experiments, consistently. Show that riding. An arrow bike offers a, substantial. And quantifiable. Advantage, over a non-arab, frame, and three. Of the top four riders currently, on GC as we make this are, actually riding arrow, bikes and I. Guess, this begs the question, what, is the advantage, that can be gained from, riding, an arrow bike throughout an entire Tour. De France well, that's interesting because Garrett, Amish and Chris Froome of both using the pin array left ten which was developed. With wind tunnel testing, and, computational. Fluid. Dynamics, right, let's remember that but, they also got the integrated cockpit on that yeah this is, gonna help yeah absolutely and you. Know the f10 is a bike that I've been told by people who've independently, tested it to be right, up there with the best area but bikes on the market and it's a very very aerodynamic, machine, and also there's no, disadvantage. To them riding it in terms of weight because they're, using the X light model which they can build to six point eight kilograms the UCI limit so there's, no arrow kept there's no weight penalty, for riding there that's incredibly good for an era by tragedy. So. Ollie I've noticed, that Tom Newman on is riding a giant TCR, which is a non-arab, bike and whilst, most. Aerodynamic. Drag is caused by the writer the. Bike still contributes, a small and not insignificant, amount, to the total drag. That's, right so, science. Of that. I contacted. Our friends at what shop who had aerodynamic. Gurus, and put this to them and done, Bigham at what shop got back to me with, the following calculation. So we're gonna flash these on screen so, that you can pause it and take, a look at, your own leisure. Now. The. Calculations, have been done based upon 19, stages, of the Tour de France so not factoring, in the two time trials, they've, also used the, average, speed based upon the average speed of last year's winner of the Tour de France because.
It Doesn't tend to vary too much it's always around 40, kilometers an hour and then. The calculations, also factoring, the benefit, of drafting, behind team, mates or in the pack and, once this has all been done it, can be estimated, that on Dumoulin, would, save 7. Watts if he were to ride an aero frame and an, aero cockpit, such as that on the propeller you know what's interesting is, that even, whilst rafting there's a significant, error gained from, riding an airframe and I didn't realize that before and, whilst 7 watts doesn't, really sound like that much I imagine, if you're constantly pedaling, 7 watts extra over the entire Tour de France that would start to add up hmm. What what does that what, does that equate to on it what. Does that equate, to, I'm. Glad you asked that Chris well, the additional energy can be expressed as. 2167. Kilojoules. Which can then be converted into, calories, and that equates to 518. Kilocalories. Now this is the energy that is, at the pedals and the human, body is in 100% efficient, is roughly 25%, efficient, so once we factor that in it, actually works out as an additional. 2071. Calories. That tom Dumoulin, will have to consume because, he's, not riding an arrow by now that. Roughly equates to one. Point two gels extra. Per, day blimey. That's seriously, starts to add up twenty, two point eight gels throughout, the entire Tour de France yeah imagine, how many times needs to go to the toilet extra because of all those gels we're going in. A bit of a problem in the past isn't it you know - crap yo sorry guys literally. Crap, Joe but. In all seriousness it, is worth stressing that this is an estimation, or be an estimation, that's been grounded, in maths and science. Win. By no means claiming, that this is definitive, no, but it is interesting because when you take into account the benefits of an arrow bike it kind of points to doom and I'm being one of if not the strongest rider in the race especially when, you consider the, time he lost on the murdered for tainted edge yeah, absolutely I mean he'd be right up they'd only be a couple of seconds behind yeah, Thomas Aaron Thomas at the time of recording this yeah I mean with such small winning. Margins in a massively, long race like, the Tour de France you. Know how you, know does a tech actually influence, the result we want to know what, you think say let us know in the comments section below you know your opinions, on this but, you know I probably. Would look at this 23 gels in a different way up I mean 23 gels I probably, swap that for five additional. Chocolate brownies you, know what when you put it like that Holly yeah that's it I'm sold, nah terabytes for me from now on just so I can eat the extra brains yeah, yeah, I'm gonna get on a bike as well more brownies. We're. Gonna now have a look at the results of the poll from. Last week some of your comments as well which, was the question how, this breaks finally, made it into professional, racing so. According. To the poll it was roughly a 60/40. Split in, favor of disc, brakes at the moment and it does look like the more we've become accustomed. To this brakes the more people, are becoming in favor of them but thanks, so much for all your comments because they're really worse than absolutely, brilliant ones and some very very.
Excellent Points made by a lot of commenters as well so should I keep off with the Diaz comment from astral thief go for it he says or she says listen, it's. Really simple rim. Brakes have that amazing iconic, look especially, with compact wheels but, disc, brakes are also good-looking especially, on the more aerodynamic, bikes and they. Function significantly. Better in all weather conditions the. Minor weight penalty, which, will soon vanish is well worth it just, lose a couple of hundred grams of body fat and, since. Pros tend to need to add weight to the UCI limit, to hit the UCI limit why, not add functional, weight instead of dead weight the, bottom line. From astra thief disc. Brakes are here to stay yeah, good points will, go another comment here from the daydreaming. Aristocrat. Who. Has, written whilst. Taking, a break from daydreaming, presumably, that. Has a lot of the graphic yeah yeah as, long as the super, techy scientific, team sky he sticks to rim brakes I'm, not, completely, convinced, by discs I think. The only advantages. Of discs after all a braking, power in the, wet and also, rim, wear or weld the lack of rim where I guess yeah I suppose the kind of onto something there if sky, aren't, using the Pinarello with discs you, would like to think there's a reason behind it, I'm a big dis fan but they've clearly person sort yeah it's intriguing yeah the next comment is from handy, Corso you actually made, some really good points about the actual mechanical. Design of current, disc brakes on road bikes oh yeah. And he says that disc brakes are currently limited by the design of deformed, square seals to retract the Pistons and this, means that the gap between the pad and the rotor is too small and it's making. Difficult alignment. However. He, does add that the bad roads that most people ride on and the oils and the other, dirts and contaminants. Invariably. End up on the, on the rotor and on the pads themselves in, bad, weather which, is also going to kind, of detract, from the braking performance that you would expect to see from the discs yeah, and he says you know makes the that's you know when you get dirt on the pads it makes a good point that that causes the almighty Banshee, wail and the loud squealing, noises that you can get with disc brakes and you. Know these noise, is a unacceptable. To most people riding they can be really annoying it's great when it's a busy place though because you don't need your bed anymore you can just sit on the brakes, I've. Definitely scared a few old ladies, at. Level crossings. But. Yeah he says sort this out and, he'll take a look at, us first Blake there I mean I would say that this brakes are brilliant but they're not perfect yeah yeah better. Than rim brakes a tie guy for more tech Wolfpack. Tires these, have been spotted on Jakob Fogle things like yeah, Wolfpack, ties are a new, company was hailing from Germany, and they're, actually headed by Wolfgang. Renne now, you may not have heard of him but, he, has had a very successful career, in bicycle. Tire development. And was previously. Credited. As working on the GP, 4000, continental, and also, the specialized, s worked turbo, cotton, why, it's obvious not tired of it yet that's quite the CV yeah, resume. If you're watching from the states Wolfpack, quite a number of new features with these including, new polymers and the race to guard compound, is low. Rolling resistance puncture. Proof and/or. Aerodynamically. Optimized, I believe yeah, Wow can't wait to have, a go on a pen amazed and see what that long next, up we have news of an. Outstanding. Ride by polish rider Marcin, via box key now be a watch he has, previously beaten, this year macaque via cough ski in the, Polish national time, trial yes, she came second ahead of fit cough ski but. This weekend, he broke well absolutely, annihilated. The British, individual. Time trial record 450, miles and, he did it in a time of one, hour 30. Minutes of 31. Seconds, which is quite, frankly ridiculous, with, an average power, of. 387. Watts, yeah. That's that's cause I'm going you know I always offer to form a teammate yours right here's yeah he's a bit special I always used to think of a fifty-mile Bart riders you know around three hours. Fifty. Three point three three nine twelve it's an hour he averaged or 33. Miles an hour that is fast, and take a look at this bike the Pinarello bolide, with a 64, tooth training which this. Time is a little smaller than what was used in the past actually but he does reppin you could use a 64, teeth on any day of the week even on your normal road bike off maybe, he could yeah. Right. Maybe. Down a big help. Margin.
Has Also put a huge, amount of effort into every, single detail on that bike years. Ago you made up his own quick-release skills I'm having Grant down and they were absolutely minuscule absolutely. No, stone is left unturned when it comes to his preparation, ultimately. He wants to take every single time I record that there is yeah, I mean well that meticulous, attention to details glia paying off because he's got a 10 25, and 50, mile records and he only, narrowly missed out 100 so he's from being they'll be back yeah. Yeah. Right, now, you may remember John's brilliant. Video where it shows you how to work a chain now this can be a lengthy process but very worthwhile, because. Of the reduced friction in your drivetrain. But now when, Drax believes, it's simplified, the process with its new rub. On chain wax. Yep. They say not, only will it keep your chain cleaner it will be quieter, and more efficiently. Because of this sophisticated formula. That's taken two years to produce it's. Basically on paraffin, and with. The sink and Teflon, additives they, guarantee, to reduce the friction in your dry run I mean mr. Miyagi's gonna happen so you love this any just wax on wax, off, brilliant. It's. Now time for the gcn tech wall of fame and this week we. Are inducting the first, well, modern bicycle as we know it the john kemp Stolley safety. Bicycle yeah, these were designed in the 1880s. A while, ago now and they were the first bikes. That resembled, the modern kind of bike, that we see nowadays with a diamond-shaped frame and wheels, of equal size yeah, say john kemp stylee designed the safety bicycle in 1885. And the first commercially. Successful sort. Of iteration, of it was the rover, now, at, the time this bike was actually, heavier, and more. Expensive. Than, the, equivalent penny, farthings, of the day can. You imagine anything, being heavier than penny farthing because. They were they were pretty, big this, bike also used in direct steering which I should imagine would have been a bit of a laughter stylus but once, they adopted direct steering like we know today these, bikes proved to be really hit yeah and they also proved to be a big hit because they were much safer, to ride than a penny farthing because you weren't so high up and this was all down to the fact that you could have smaller wheels and this, was because the, drivetrain mechanism, was very, similar to what we have now so you had the chain ring drive system where you had a large chain ring at the front and a smaller sprocket at the back meaning, that you could have a smaller effective, wheel size and still get the same speed so you, know you compare to the penny farthing which had it sort of know, by drivetrain. Where, the pedals were directly, attached on to the front wheels she needed that massive wheel even more direct than a fixie would be yeah for, viewers elsewhere the ovum, and wheel company found that in 1882, were these first mass producers, of the safety bicycle in the United States they built these from their Factory in Massachusetts, oh good.
Okay. Well, as, ever leave your suggestions, in the comment section below for future, submissions into. The wall of fame and, stay. Tuned for more next week can you imagine where we'd be though without the safety bike on it yeah well I can't, but we wouldn't have jobs or we'd, be riding penny farthings yeah next. Up Olli is bike of the week yeah. And last week we have the Scot foil of Anamika fan falutin versus, Luke, Rose Pinarello, k10. With high right suspension. We did and the result is with, 71%. Of the Rope of the vote. Anna. Meat from floating's scuffle, I did vote for it's. Cool it's a very nice bike yeah this, week we've got two quite different but customized, bikes so firstly we have sylvain. Chavanel, willya. Chen toe 10 versus. Roman. Bar days custom. Factor. Oh - these, are both pretty heavily customised but one's a narrow bike, one's not a narrow bike what, you go for ollie yeah oh I've. Really liked that little detailing, on on the bar days bike it is pretty cool but I just I love the discs on Plus also if you ride bar days bike because not an error but you get to eat five more brownies good, point yeah what do you write guys reckon why, not though. It's. Now time for, the bike fall and this is my favorite bit yeah I love this I just love looking at pictures of people's bikes to be honest money first. Up we have well. This this is a familiar-looking buy to me we've, got, no. Ordinary, titanium, bike as Scott says it's, an enigma Excel and more importantly it's previously, beaten mr., OPN seated Sprint's what, he's. Let himself down here already, it's. Been a bike which Chris has spent many hours staring, out into light around, the corniche lanes whilst, we trained together over the years okay some of that's true Scott so, she'd point out this is one of your mates you serve his in this, is one of my mates it looks like I'm being stitched up here a little bit but, this is is quite a cool bike he's got SRAM e tap which I love it's got a e brake, set which I know is a lot of hassle to get running smooth very light though very, very light speed plate pedals, vision, 35 wheels Envy, fork tubeless, tires, it's. Got a unique magic, hands Cornish emblem stick it on the top tube which I can explain in the show Scott's a physio and he's known locally.
As Magic. Hands anyway, this. Picture, depicts what riding in kono is about a road less traveled to which there are many if, it's not a super cool than I'm in trouble while. Scott taking, a picture like that I think well I'm, gonna take issue with this firstly, the bottle cages and. What's going on there they don't match mismatched, bottle cage I. Mean, that wheel. Wonky. Wheel placement, for the photo no, there's no super nice from this this week Scott it's just getting a nice its. Intelligence, a nice bite that's, punishment for your cheeky comments come. On on to the next one next up we have a submission from a rough almanarah, who, is from New Yorker but will be living for a few months in Sergi little. Town in France near Geneva and this is because he'll be working at Sun yeah. I will just. Hope he doesn't have a collision. Yeah. Hadron, Collider, do you reckon that's like an indoor tunnel maybe he's doing it's massive seen it seen them see I brought, my bike with me and I'm sending you a photo of my first ride here the, photo was taken on top of the cold that I first seal and that is, in the Hort here at National Park I, hope, you liked the photo can, you give it super nice he's, got these nice felt there as in the ears I love it yeah I'm read really feeling I felt yeah, it's. Beautiful, I like the ways against. That background as well nice it's. All green in just it just looks like a nice place to go for a bar doesn't it it does look good but that is a really nice-looking buy quite. Like the way that the bottles the blue is offset against the glue is super, nice John get my super nice on it. Next. Up we have this absolutely. Awesome Scott. Speedster. From Tony, now, I absolutely, love, this but his loads of cool detail so Tony says he, bought the frame roughly. Sort of 10 years ago and he's had, it a long time and upgraded, it and now he's upgraded it to 11, speed Oh Tegra, and, apart. From the S FSA, SLK like crankset, it's. All or Tegra now he's basically. Watched, our video on stuff, that the UCI has banned and so he's poor his spinergy. Rev. X's out of retirement so, they're really cool wheels that mario Cipollini used, to ride, but. That's really bling I love the little yellow. Bits on the spokes the wheels the way they systole match their well not so subtly but they match their the red in yellow on the. Chain set and the pedals as well that's nice a nice bit of color coordination well, is the red bar tape and, the red stubble as well it's such an iconic look and the fact that you've had to mill and fire the way at your rear wheel and your cassette just to get it to fit I think that's, really, deserving yes you want proper, good hack but I just love that mirrored, finish.
On The Scott speeds the frame as well yeah just a really cool bike guys. Without, a doubt. Super. Super nice see on the bail next. Up we've got a submission, from, Martin Liang in Singapore, who built this bike up himself in December 2016, backplane it's got some pretty cool features and, he's clearly gone for function over fashion on this bike he, has a severe os3, disc frame from 2017. SRAM eat app hydro, which is pretty, cool. Smile. Tegra a six hundred six thousand eight hundred cranks. 50:34. Whose symmetric, compact rings 18. Tooth. Put. Is to raelia yeah, 60. Mil front room 88, mm rear room with onyx disk hubs Shimano. SPD, pedals and only. Weighs eight point five kilos, yes impressive, for a you, know bike this will arrow and with this brakes are so free yes wait but, I look. At that bike and I can clearly see that's a guy that knows his, self is a very specific and individualized, set up for clearly what he wants yeah on a bike and yeah I respect, that so it's got many different colors there as well yeah it's very functional it function. Function, function this that's what this bike that says to me so what have you seen the bar and it's even got a lion, which, is pretty cool so you're gonna go nice or super nice model Chris I'm a big fan of function, over fashion so I'm going super nice. Next. Up we have this bright yellow Santacruz, stigmata. From, david saps furred thanks for sending that in David. Haven't. Really big fan of this buy it's just such a simple looking, very, clean. Bike, and I, really. Like the way that the bar, tape is just perfectly color-coordinated, with the Santa Cruz grey logo on the frame it's just like a subtle bit of color coordination but, it just really sets, it off you know you know what I like is the simplicity of it it just really smart really neat nothing, too fussy or fancy just a lovely really cool looking bike yeah, and, interesting. Bottle cages on there as well I'm not sure what brand they are maybe you can message us and tell us what they are but I'm not seeing this before yeah. That's a super nice for me going on it ring the bell. If. You want to submit your bike, to the bike fault then simply, send, your picture of your bike with, your name and location, to, the email address which is on the screen now that's, it for another week on the tech show what's coming up so, on Saturday. We have Roman bar days Pro bike which is particularly. Nice one's very custom, and then. On some day we've got another GCM tech unboxing. Which means you have a chance to win some Roca sunglasses, and on Monday it's back in the maintenance room with John Kennex yeah and if, you'd like to purchase one, of these absolutely awesome limited. Edition yellow, very. Seasonal, GC, on t-shirts, once they go on the gun yeah then check out the gcn shop which there's a link here, and then, if you'd like to watch another tech video then why not check out the unboxing that, I do earlier in the week of the wahoo kicker and kicker headwind, for a chance to win that's, a pretty cool prize it's all surprise.
