I can't speak to the intentional rationales behind the Lotus bike, but it seems more of a matter of allowing reduced air resistance to wheel movement, and maybe softening the air before it hits the legs with the ultra-wide fork. This is all less of a tactic of deflection around certain areas though as just putting the things that catch air mostly in line with each other.

Victor is probably deflecting air mostly around his thighs rather than just "softening" it. I would bet that there is effectively a pocket of air under his chest & belly that is moving right along with him because of the very closed off front end. I have no evidence for this. But I think that's essentially the goal of an air deflection strategy, rather than a strategy of just breaking the air first before it subsequently impacts another component of the rider-bike system albeit with less effective velocity than it would have if unimpeded.

I'm told he removed the visor himself to get more ventilation.

Those "obsolete" helmets are being produced again, undoubtedly due to POC noticing that the ones on the secondary market have been selling for multiples of the original retail price following the success of the HUUB/Wattbike team (and others) using them on the track.

I wonder if Jim from ERO tested Besseger. Supposedly his road position is a hair under .18. Any comment Jim?

Typically when socks are too long, guys just pull them down a little. Then once they're past the UCI check they pull them back up. :)




Some people with good knowledge consider the Tempor to be the fastest for some people. POC actually brought it back into production this past year due to demand. As for the looks, it looks great when you win.

I love the POC. Bonus watts for ducks.

It is by far the fastest for me.

I'm getting a kick out of seeing a lot of these new(er) fast fits look as much like the Obree "egg" position as is possible given materials constraints.

True Dat. I like that he ripped the shield off that helmet before the final climb.

The Tempor is an oldy but goody product. I think the reason for POC doing another production run was more for all the track teams that wanted to use it for the Olympics. I think the term “obsolete” is appropriate if you want to talk about comfort and usability. The visor attachment sucks, the quality of the lens is so-so, there is nothing like the MIPS on the inside and fit adjustments just plain suck. Nevertheless, If it works for you, it works really well. I have had people tell me to “name your price” to buy mine and there is no way I am selling. Even if I got $1000, I couldn’t buy as much speed as I lost.

None of that is obsolescence, it's just the product being exactly what it was designed to be; the fastest helmet they could make for Gustav Larsson to ride at the Olympics, to hell with anything else, including aesthetics and ease of use for some age group triathlete that might want to wear the thing at some point down the road.

POC started producing the Tempor again. They're freely available (in the UK at least)
e.g. https://www.gohelmets.co.uk/...2197?variant=403-361

I've seen bare legs test faster than many of the brands of socks that claim to be aero and faster than tall socks.



Some helmets are designed around the eye shield, it's part of what make the helmet so fast. other helmets throw it on as an after thought or it makes no difference. IDK if he started that way, maybe it fell off?

Hard to disagree with this one. If you pause the video at 1:30 you can see some of his test results. 40-41 kph on 200 W. With a noted tha the most aggressive position (guessing the 41 kph) is not to be used and position to match what he had on the Ridley. I am about the same height as Vic and have averaged 40 kph on flat courses with little wind on 216 W, 41 kph on 200 W even on the velodrome, is very good.

Having said that, no socks seems a bit weird to me. He only placed 59th so he wasn't pushing 100% (was runner up to Ganna last year on a good year), maybe just riding for comfort that day?

Hello ianpeace and All,

Cool, under 1kg rim brake disc....

All those who say rim brakes are inferior on a technical TT course, already blew a gasket.
No need to trigger.

Nice looking wheel. Retail price of $5700. LOL.

Give it 10 years. I envision aero wheels that instead of more rigid carbon are made of light weight amorphous solids that can alter their shape based on the yaw angle presented to them. $10000 per wheel.

And then the UCI will ban them.

Why would any company invest in R&D only to be banned as soon as people see the potential ?

Well, in the US exactly 1 in 10000 buyers of aero wheels likely need to abide by UCI rules even in USAC time trial events.

Just sayin.

And how many will pay the $10k per wheel ?

Just askin :-)

Anyone live in the UK and want to ship me one? I'll PayPal immediately for helmet cost, shipping cost, and compensate for your time. DM me or reply here.

I'm in Tucson, AZ, USA.

I heard this was due to strong demand for the next movie of the start wars saga.

The Citec Ultra has 800g and costs one third ...

So I wasn't familiar with Citec wheels until this comment and I just looked into them. Their specs are almost unreal. Like how are they able to do a 12 spoke front wheel when pretty much no one else is able to do under 16?

You can build a wheel with a handful of spokes if you want, that doesn't mean it's very good or will stay true for very long.
