The brand is a client of mine. Along with the extensions, the 100mm front (and a new disc) are development projects ENVE has been working on with UAE for his assault on the double. I can’t find it, but saw a picture the other day of him cooling down on TT bike with the badged front.
That’s not the same wheel that’s been used so far this year. From what I can tell this has internal nipples and no valve cover. They’ve been on AeroCoach Titan so far which has external nipples and a valve cover.
Looking forward to more information on the new one.
McNulty rode it at nats and I’m pretty sure Pogacar rode it for both Giro stages. Public launch should be later this year.
I haven’t checked what McNulty was on for nats, but Pogacar was on AeroCoach in Giro in the picture I posted earlier. It needs to be on the approved wheels list to be ridden in UCI TTs this year which it isn’t at this moment and explains why it wasn’t used so far in international competitions - they don’t usually check this stuff at nats so you can pretty much skirt these rules if you want to there.
Doesn’t seem like a large delta from -10 deg to 10 deg. Pretty marginal gains. For $120/tire, not sure it’s worth it. How often do we really see yaw beyond 10 degrees?
My hunch is that’s going to be hard to beat the Vittoria on majority of the courses.
For the riders that manage to survive to the Stage 21 Time Trial, there will be some “real world” testing -
(ALL CREDIT to www.letour.fr) From about 19km to about 28km, approximately -5.5% !!!
I just put one in my cart, figured for $120 I could try it out with my aero sensor and at least entertain myself for a bit with it. But they wanted $66 to ship it. So it’s not a $120 tire, it’s a $186 tire, at least if you live in the US. Hopefully the regular outlets get the tire.
Also, related to the front page article comment about ‘first ever aero tire’, there used to be a Bontrager aero tire. It’s gimmick was that it filled or smoothed out the gap between the wheel and the tire.
I don’t know how often in average, but I’ve done TT courses where the entire course was a bit over 10 degrees. Even around bike average bike speed. A rectangle with a crosswind diagonally across the rectangle, and a stiff desert wind.
Edit: Granted, some of that is quartering tail, which I’m not sure counts as much.

someone on the call said first one ever,
someone else said first one that ever worked.
And Marc will be doing some additional testing for real world stuff, too.
Pretty excited by this one.
That was a really good write up. Clear, concise, informative way beyond marketing speak. Really looking forward to what testing can look like.
correct
i wonder does swiss side indirectly suggest the zipp dimples are working…
nah. They were very specific. You need the right shape
Today I was testing a TriSpoke in Girona. We saw the wind turn about half way through the tests and we got a nice crosswind.
About 10deg yaw and the rider could feel the wheel twitching.
I can see it in the data. It would have been great to have these tires on a separate wheel

Any rolling resistance data?
How much does the TT TR cost in your country? I assume the difference is maybe $20, for the same or more gains than a cockpit change, new helmet, etc (which all need an aero test to verify). The W/$ is pretty high on these and will be the same for all riders.
In Europe you find the TT TR for 60eur and this new one is priced at 120eur (+shipping through swissside). Not sure if the aero 111 will also be found at standard retailers?
Edit: yes, already on bike24 for example.

I can get a TT for $75 in the US. I’m not really seeing the total watts saved on these compared to a TT or the corsa pro speed when you factor in crr unless you ride in high yaw conditions (>+/-10 deg). It appears that one would save ~1-2 watt -10 to 10 deg against most other top tires aero wise. But then you are giving up crr compared to a TT and a lot more to a corsa pro speed.

Flo did a study years ago about yaw angles where they found 80% of riding was between -10 to 10 deg of yaw. Not sure if there has been any recent studies saying otherwise or specific courses that see higher yaw than others. https://blog.flocycling.com/...tep-2-data-analysis/
Tom Anhalt used to say “crr makes up for a lot of aero sinsâ€.
My first question is does the Vittoria-Conti delta given by BRR is pan out on the road. My guess is no
Next is to see what the new Conti does at -10 to -20. Do their claims measured in a wind tunnel pan out in a turbulent environment. Ask Hambini what he thinks
Then we can see the delta
Then we can decide if that delta is worth the puncture resistance improvement and $
