Aero tires are here... SwissSide - Continental aero 111

[C36]

JP Balard did mention working on real aero tires and some members shared the link with the patent and along the new Van Rysel Aero FCR frame they will start the TDF with this aero tire. CN publises the first pictures

I need to revert back to the podcast but gains were fairly huge (way above what a deep section wheel will give you).

[EtoDemerzel]

basically a deeper groove GP5k. what are the watt savings?

I hope they use the 5000 TT tire as the base for this. Not the normal 5000. Otherwise the TT may still be the better tire in many instances

[C36]

There is 1.5w difference between the GP5K and the TT. from JP's interview on EC, there is way way more to gain on the tire improving the entire front end aero. I want to believe a double digit gain is not imposible at high speeds.
Without special development, between a Schwable TT and a Vittoria Corsa Speed you already have 3W of aero difference (45KPH)

I think you'll get 2W over GP5k at 40-45 kph at most as it's already one of the most aero tires, espically as double digits (10W) is about what you'll see switching from a modern 35mm rim to a 80mm rim. The Corsa Speeds is also one of the least aero tires due to the raised thread cap.

You can even see that here. Going from a 22mm tire on a CLX 64 (the width and tire the wheel was designed for) to a similarly increadily unaero 26mm tire had nowhere near 10W of gain.

Good look at the tire here

Deep beveled chamfers looks like they are acting as turbulators.

Already available. Price is ... high

Tour has posted very detailed graphs (I know we have some fans of drag versus yaw angles)

https://www.tour-magazin.de/kaufberatun ... de-france/

Few graphs (yes its ugly) I quickly piled up comparing, the 26 versus the 29mm tire on the same wheel (DT50mm) and on relatively narrow (DT50, versus super wide Roval CLX)

26mm Aero111 tire / 29mm on DT: 0.0013m² difference


26mm Aero111 tire on DT 50mm / 29mm tire on Roval CLX Team : 0.0017m² difference

On slow twitch it was mentioned that this fires is somehweee between the TT and normal 5000 in rolling resistance. As it's only faster past 10 degrees if use (where people are rarely at), I think it'll be a wash most of the time vs as 5000 TT

To me the shinniest part is its linearity feedback of the Xwind Yaw, which can help a lot in mountain area where the wind changes rapidly.

I have had this tire on my front wheel for about a month now. I wanted to try it out because I experience gusty winds from time to time which can make it interesting on high speed descents even with a relatively shallow front wheel (Enve 3.4).

My experience has been very positive. The best way I can describe it is that when the wind hits, it no longer wants to strongly jerk the front wheel off to the side. Instead, it moves a little bit then seems to reach a steady-state. I have actually had to get used to the sensation because my instinct is to want to counter-steer when experiencing a strong sidewind and I no longer have to do that.
