That Guerciotti is an open mould Chinese frame, which is freakin awesome. Very cool to see riders at the top of the sport using equipment that just works, and doesn't have to have millions in marketing behind it.
Indeed it is. It is the same as Vitus Chrono TT 2 and some Chinese brand TT bikes. It looks to be a DengFu FM086 frame with different rear brake design.
9:14 that's a silca speedshield that makes the valve more aerodynamic but I suppose it does stop rattling as well. Those De Rosa TT bikes are beautiful..
TT-tech crazyness like this mainly makes me wish, that we would simplify cycling again. Why not follow the standardized rules for road bikes in TT too. It would make life much easier for aspiring riders just to deal with one bike.
John is AWESOME! I absolutely treasure his experience and passionate enthusiasm for tech. Please continue to have his informed fervour featured in future tech features.
A shot of Yates bar set up would be good. I looks like his running something similar to the carbon wasp extensions Huub Watt bike run on the track. Like the speedbars on the Flying Moustache, but without the built in arm cups as it looks like he is still running the Aerocoach highsided cups. The rubber bits on the wheels are actually for aerodynamics to shield the valve and are by Silca (they come in their wheel balancing Kit).
Not sure which bit of tech is my favorite--let me think on it--just thanks, Jon, for your close-ups of all those bikes. Each looks like a mighty locomotive ready for some serious locomotion.
That indeed appears to be a HED 3 (GT3 version?) wheel. Used to have the clincher version with alu brake surface. A super fast but truly terrifying wheel if the wind hit it from the wrong angle!
The dimple-bottle has the added benefit of being easier to grab while riding. Those aero bottle cages can clinch those bottles really tight, especially when new, so by making it grippier the rider won’t get as distracted when he’s trying to pry out that bottle. That’s my experience with Profile Designs bottles at least.
Would love a video on Pozzovivo's TT bike, if only to get a proper square-on shot of that posish. Bet it looks reet cool. Love it when the extensions are in line with the top tube.
The piece in the front wheel valve is to compensate the weight over the wheel, if not the weight is not equally distributed over the wheel and is not as stable, potentially being slower
It’s very common in the UK TT scene to not have any bar tape or grip tape or gloves. Your hands are in the wind so they don’t really get sweaty/ slippy. Only time its dodgy is if it rains but then you’ll have gloves.
@@wrxzboost ive seen machincs use small black magnets like they will use on spokes with speedmeters. You dont have to specifcly use the silca weight. Just something that counterweights the valve.
@@stewpowell9294 Exactly, depening on wich manafacturer and true of the wheel you will have to put a tiny amount of weight on the other half of the wheel. Normally to balance it and make it true..
The cover on the ef time trial bike is from Silca and is actually more aerodynamic, saving about 0.5-1watt I think they said. Not to do with it rattling although it probably does help that too
both enve and specialized have tubeless ready disc wheels, Jon and that valve cover on team EF's bikes is so you can tighten the nut firmly against the fragile carbon rim
The pizza slice with a cap on is to represent the name of the cannondale disc tt bike called the super slice and the trispoke on the moviestar bike looks like a hed gt3
#AskGCNTech - Jon, what are the requirements of the UCI for pro's when it comes to equipment? Specifically, since the UCI states items must be commercially available or be made available within 120 days from prototype authorization period, how does this apply to Time Trial bikes vs their regular road bikes given the high degree of customization? Where does the idea of "equipment" end - TT vs Road? at the pads/non-slip adaptations? at the (CNC'd) risers? customized but bought equipment? Perhaps certain anthropomorphic exceptions are made (short or tall)?
@@LoekZweers That does raise another point - UCI says the pricing can't be such that it's really a de facto private production. (Of course if the mfr does make enuf of the Sky bars, price should be way cheaper.)
12:05 Pro 3-spoke wheel mounted backwards. The blades are directional air-foils and are faster when spinning the correct direction. Mechanics are not physicists and don't understand the equipment given them to install on the bike. The best equipment is no advantage if the mechanics don't understand how to use it or install it.
Are you referring to the fact that these super slices have rim brakes and the ones commercially available come in disc brake only? I was wondering about that.
John needs to work on his TT equipment knowledge. 6:42 is the new Kismet Carbon Pads made by UK TT legend Matt Bottrill as he has been working with some of the riders from that team to make them more aero. 9:41 is a silca speed balance. It would be good to get some footage of the diffrent styles of tt extentions used.
@@JonCannings It's this silca.cc/products/tubeless-valve-kit-w-speed-shield Protects the rim from tubeless nut valve and makes the valve more aero. Silca speed balance goes opposite the valve.
@5:00 I'm going to call BS on that bearing test. the weight of the wheel alone doesn't count as load and ~64KM/hr isn't particularly reasonable as a speed anyways. the spin down test would have included air friction from the rotating wheel. Also is it a full ceramic bearing or a hybrid where the races are steel and the balls are ceramic.
Andrew Meyer -- I wouldn't imagine they'd use sealant because of the weight penalty X 3. Most pros use the ultra lightest tire their sponsor makes on the front, something with some puncture resistance on rear because most punctures are on the rear. Eddie Merckx would walk the pits in the morning watching his competitor's bikes. The ones with the lightest tires were the riders he'd look out for that day.
@@happydays8171 sounds like an urban legend rather than a true story, or he did it only a couple of times. Surely knowing the riders themselves, he'd know who to watch.
@@happydays8171 I call BS on that. The UCI has been very lax enforcing this rule. I even wrote to the UCI a few years ago requesting an explanation for this - it wasn't material to me, but it pissed me off that I couldn't get some parts for my TT bike. This is in the days of Julien Carron as technical coordinator, and the infamous UCI sticker issues. You don't believe me? Try to get some of the custom components used by Sky/GB, like the 3D printed handlebars. You could try to get a quote (it'd be insane), and simply be put at a waiting list beyond the 120 day period. Even the Kask Bambinos took almost a full season to be available for retail.
The silca valve thing us because you have to tighten the valve down for tubless purposes, and you don't want the point pressure on the inside of your rim. #gcntech
@gcntech can you ask cannondale mechanics why their superslice tt bike is sold as disc brakes, but pros ride it with rim brake. It’s so lame to see as disc tt bike with rim brakes. Cannondale your cool points are gone on this bike now.
What’s the purpose of tubeless tyres on tt bikes, on mtb they offer the advantage of lower pressure without the risk of pinch flats but what advantages do they provide on a road bike? Are they just a marketing trend like disc brakes?
It's all about rolling resistance. No tube means softer tyre, which means possibility for lower rolling resistance, and better grip. Similar to what latex tubes offer.
Boris Cid Vidal -- I bought some tubeless rims on sale, 1/2 off. Best handling tires ever! I put my clinchers back on, the bike fights me going into turns. With tubeless, you look at a line you want to follow through a curve and the bike follows effortlessly. This explains why Peter Sagan is so fast on the decents, he's pushing them to the limit.
objectively lower rolling resistance, as measured on a steel drum. For sure it's a marketing trend, but same as the disc brakes it won't make a commoner into a pro. It's only small advantages that may or not accumulate. Yet you still the same 2 dozen riders winning 80% plus of the prestigious races. Quite amazing.
so we are back at trispoke wheels... didn't we have them about 20 or 30 years ago. Then they found out, that normal spoke are more aerodynamic. most of this shi** is just marketing.
Ghostflasher depending on the particular fork, a trispoke is a very fast wheel, faster than almost any spoked wheel. The key is pairing it with the right tire. If not, you wouldn’t see the likes of Dumoulin, Wiggins, R. Dennis, Campenaerts, etc... frequently using them.
@@scotth3354 I didn't say that it isn't a fast wheel. It's just funny how they sell it again as the holy grail of aero. And yeah, the top pro ride these wheels but most of them don't really care about the material as long as it is not absolute crap.

Who do you think has the nicest bike or the coolest piece of tech? Let us know in the comments below 🔥
That aero bar under the handle bar cause I'm also quite a short rider
I believe that Tri spoke is an old Hed, I know at one time they were the fastest front wheel in the TT!
I really like the looks of the standard EF Education road bike.
that Cannondale looks pretty fantastic to me, and I'm not usually a huge Cannondale fan
The Cervelo p5
That "emblem" is a SUPER pizza SLICE... the cannondale model is called SuperSlice, so they took a slice of pizza and got it a cape....
Nice to see Diego Maradona has landed a job as a bike mechanic for the EF. 9:55

I can watch Victor Campenearts Time Trial for 5years in a loop. The guy looks so steady, unbelievably low, aero and powerful.
And no glasses!
Ger I think he said it is about better cooling

@@gerardobaxana it appears to be the GT3 version from what I can see.
totally agree, no way that HEDs geometry is freely available to other manufactures - probably a HED that has been customed by the team mechanics.
That Movistar 3 spoke is a HED GT3

The pizza emblem under the fork resembles the bike "Super Slice"

The cover on the valve is actually for aerodynamics. But I guess that noise reduction helps too
its also a small weight so you can straighten the wheel to it maximal extends.
@@wonglemydongle867 i'm surprised it's not trued with another weight on the opposite side of the wheel.
@@wrxzboost ive seen machincs use small black magnets like they will use on spokes with speedmeters. You dont have to specifcly use the silca weight. Just something that counterweights the valve.
Surly to balance a wheel and offset the rotational weight of the valve the weight need to be opposite the valve and not adding more mass at the valve.

That team trek with the one by seems to have the sram 12 sp chain class
11:30 That emblem is a slice of pizza with a super cape! 😂🍕 The fuel for all cyclists.
The Vision Metro rear disc wheel at 8.32 seems to have a gap between the rim and the tyre. It does not seem very aero tuned.
The pizza slice with a cap on is to represent the name of the cannondale disc tt bike called the super slice and the trispoke on the moviestar bike looks like a hed gt3

Lego acc hold the record for most bike tires produced each year😂
I wonder why they don't have angled bars, much more aerodynamic in a semi "mantis", maybe it's a flexibility thing

how rusty are those bolts on the fdj tt bikes
