British Cycling released this week their custom track bike they will be using at the Tokyo Olympics 2020 next year. Cycling Pulse ventured to Roleur in London and got some close up footage of this new track bike so in this video I analyse the design of the track bike and why British track cycling has developed it

in the biggest news of British Cycling this week they’ve unveiled a new space-age track bike welcome back to the Lantern Rouge YouTube channel this is an inside look at the British cycling track bike they’ve unveiled they’ll be used by the British track team for the Tokyo 2020 Olympics this is footage e one have seen before unless you follow cycling pulse on Instagram that’s where this originated from Olli of cycling pulse who as you know I’m partnered with for the Roush support he hooked me up with this footage so let’s break it down obviously the most unique thing about the front of this bike is the flared fork which instead of attaching to the bottom of the head tube where that flat bar is just just above the wheel just above the tire the fled fork actually goes up tapers in and attaches to the top of the head tube one thing I noticed as well here is that big cutout in the carbon pipe wheel at the front I’m not sure if that’s for the storing testosterone patches or not obviously this necessitates a proprietary handlebar setup so proprietary handlebars pretty normal head tube otherwise in terms of shaping and then the fork really flares out and this one thing I noticed as well where the full at the end of the fork where it tapers in there’s actually this excess material at the back of the fork where it attaches to I’m not sure it well that is if that’s a wheel axle or the axle or not though where it attaches to the wheel it is that excess material and if you look at your the fork back on my BM see if you look at your normal road bike for they taper right in and they’re actually quite thin at the bottom maybe that’s standard on track bikes I’m no specialist three track bikes but another side as well I was interesting in terms of the actual body of the frame to hope hope as well hope collaboration with Lotus didn’t see anything too exciting especially the bottom bracket really the crank set this looks like a two-piece crank set so obviously you have the actual chain rings and then the crank arms will probably have to be you know interchangeable for each rider so it’s not a complete one piece crank set I don’t think judging from the five or six bolts there to attach that to the chain rings if you’ve seen this bike already or after this video comment down below what you think about the design why you think certain design choices have been made it’s pretty interesting design that’s for sure so nothing too unusual at the bottom bracket area that looks pretty standard but then getting to the the second weirdest part or the joint weirdest part about this bike is the flared seat stays which is similar to how the fork is super strange and unusual and out there the seat stays are really different so again if you look at my bike in the background most seat stays in on time trial bike which other diagonal ones go in that direction they normally attached below the top tube and to the seats tube so they’ll attach the seat tube below the top tube on the bike where as you see here they attach above the top tube some of the have a force at the front they flare out and they’re attached at the top of the head tube these seat stays attached right at the top of the seat tube where the seat post actually is inserted into that whatever this weld is there’s actually kind of surprised with the seat post design they’ve got here the seat post finishes with a square hard edge at the back whereas all the rest of the bike particularly the seat stays and the the forks they’ve tapered down to a narrow service area to a point where as this is obviously a hard square edge so maybe that maybe they’re modeling says that seat post aerodynamics don’t matter so much and the reason I think they’ve got these flared seat stays is because if you look at the images where you see the riders on the bike the seat stays are actually behind the riders legs seem to be behind the riders legs pretty evenly so maybe that provides like a tail tail cam effect or whatever it’s called where it increases the surface area of which the wind gets to finish off around the riders legs instead of going around just the riders legs it goes towards the seat stays who knows maybe it doesn’t mean anything at all maybe I’m just making that up probably in you may be wondering why a British Cycling getting like a proprietary custom made track bike and British Cycling I’ve actually had proprietary bikes track bikes for their riders for a number of years this is Rebecca Romero in 2008 Beijing Olympics riding on some proprietary custom track bike you see the design differences to this new hope’ track bike only the 2012 Olympics Bradley Wiggins he wrote a custom bike not sure what brand did it or what design was there but in 2012 when he won gold at London Olympics in the men’s time trial road time trial he was on a proprietary bike and the reason these proprietary bikes are being developed because track cycling is the most important event for Great Britain in the Olympics 2008 eight gold medals 2012 eight gold medals 2016 six gold medals I think on the track so they’re gold medals formed about 20 between 20 to 25 percent of Great Britain’s overall gold medals eight for the last three Olympics have been on the track so because that a lot of money gets poured into track cycling by organizations government organ in Great Britain they’ve got a big budget they got a secret squirrel crew apparently in the Manchester Velodrome that always looking for new age ways to increase performance gains other than that hope you enjoyed this quick breakdown if you want to see my rantings and ravings check me out on instagram the lantern Rouge I post there pretty much stories daily probably multiple stories and that’s really the best place to interact with me if you want to reach out via DM to chat about cycling or hit me up with any of you video ideas and like the video subscribe if you haven’t already and I’ll see you later ciao

  1. That was a good analysis. To go through the points in turn.

    The area around the forks which has the extended section (dropouts) is shaped like that to make the air less turbulent, the fixing will be a loss so this is an aim to reduce that. The aim of the game is to move air out of the way and back as gently as possible. This is why aerofoils are blunt at the front and taper down. The tapering is required because the air is under an unfavourable pressure gradient and is more likely to "break away" or separate.

    I think the seat post is shaped the way it is to make it stiffer. If you went to a tapering aerofoil, the stiffness in the direction of travel is comparatively much worse than the flat back. The aerodynamics around the seatpost are not well studied and will vary from rider to rider, the oscillating motion of the rider's legs causes disturbance that are extremely difficult to model in CFD – even a difference in rider geometry (ie longer legs) would affect the aerodynamics. In short, I think they had to choose between the aero and the stiffness and that was a compromise.

    The raised seat stays at the back of the bike are positioned to make it stiffer and they have moved them out so the rider legs create turbulence and the seat stays are moving in that turbulent low velocity dirty air. It would be a kin to getting a tow from a tractor.

  2. Hambini's channel has a good bit on turbulent air flow which gives some insight on why forks connect above stem post and why seat stays connect above top tube

  3. Germans used to have a similar program (still have?). If you see photos of their national team on FES bikes, that's them (Institut für Forschung und Entwicklung von Sportgeräten).

  4. How badly I want to see the pro peloton ride something crazy like this I cannot put into words. It will only make the sport more exciting.

  5. Great job showing details, moving stays away from wheels & be foils, not ovals is the way to drop drag any bike.

    The bummer that Windcheetah & Lotus cutaways where banned, screw the bb rule, it killed steel in the peloton, moving the dt above the front derailleur is 1mi/1.6km per hour over distance.

    Bike polo frames were solid, so, it saves about a mile in 11mi of riding same wattage.

    Scale that to cheap bikes ridden globally as commuters daily, the savings in food for all those people is megatons a day.

    Nobody at UCI ever addressed my emails and even sent a letter pointing out it's just as strong, only requires changing the dt, lighter … without it legal in the peloton it won't sell the reality.
    Ýmmv.

  6. Obeying the letter of the UCI rules, if not the spirit. Really wish the UCI would relax rules on double-triangle design etc for track and TT stages.

  7. I like the little hole at the top of the seat stays where it looks like you can hold a mini-syringe. Never know when you need a little more juice

  8. It is very interesting to compare this bike design with the rules of cycling and how they enabled this bike to happen. I’d question the width of the bike but they certainly appear to be within the lines from side on. UK have always had some of the most cutting edge stuff on the track but our BT bikes were in my opinion, the best. The Edge was and still is the most incredible track sprint bike built. We are crazy going away from those bikes.

  9. The dog needs an aero trim. Lotus could advise on the most streamlined cut – they've been blunt-force testing in aerodynamics since the 1950s. As you and Hambini suggest, this is a collaboration between material science, the mechanics of cycling, the utility of adjusting the bike, and the aerodynamics. There's a lot more aerofoils going on here than I've ever seen on a bike. I'd love to see the CFD on this thing. It's a beast.

  10. I think the reason why the seat post has the square back is because when ever you would put torque on it to tighten the seat post the back would probably snap off

  11. So hears the thing. BC are pretty good being stupid fast at the Olympics on the track. Some of this is due to new technology being released that other countries can't match.
    This is a little different though, since this is being release 9 or 10 months before the Olympics. I would think that some other federations have time to copy / mimic a similar design to match the speed of this bike.

    I also can't believe this bike is within the UCI rules. It looks so outlandish that the UCI are probably scratching their head and wondering what they missed in the rulebook.

    Will it be banned before Tokyo 2020?
    Is that the point? Maybe BC want it banned so other teams can't take advantage either…
    Will another bike brand be able to match this bike and then have it used by another Country at the Olympics?

  12. The squared off or D shaped seat posts are supposed to be for comfort, the rear of the seat post can flex, maybe that's more important than aero over the long run, if doing a seated hour record or something.

  13. The older black bikes were just branded "UKSI" and have been in use since around 2004 Athens Olympics Apparently the frames are super stiff and strong
