Tyre choice for Enve SMART wheels

[NGMN]

One thing that Zipp has talked about with regard to tires, is that even though wider tires "look" better, in lining up with the rim and filling the tire bed on the new ultra wide wheels, often times the 21-23mm tires are still faster aerodynamically.

I know Enve recommends 22-23mm tubulars, does that hold true for the clinchers as well. The internal rim width is supposedly 18mm on the front rim. Sounds awfully wide for a 22m tire. What are people using on the clincher version of the Smart system wheels?
I would love to know these are compatible with veloflex master 23mm

Thanks

I used the 23mm Vittoria's and it was perfect on the clinchers. Also had a client use the 25mm Vittoria and he reported it was a very plush ride.

I used veloflex carbon and now schwalbe ultremo ht in 23

I opted for the cx 25's. The decision for the 25's over the 23's was simple I didn't feel comfortable seeing the rim being wider than the tubular. Feel fast and work well, little better than my 404 FC clinchers.

I hope that this wider tub will offer a bit of protection if I slam a pot hole or something. Just my view as they don't have mp3 option with enve.

I have Conti 23c 4000s on my Enve 3.4 SES clinchers and with the width of the rim the tire ends up measuring 25c on the from and 24c on the rear. BTW easily the best riding bomb proof wheel set i have ever ridden.

We tested the 6.7's with Vittoria Corsa Evo CX 21, 23 and 25mm tubulars during out last wheel test. 21mm is fastest at most yaw angles. 25 pulls ahead at really high yaw (15, 20). 23 and 25 are virtually identical from -5 to 5, but 23 pulls way ahead at 10.

In other words, 23 seems the best all-around (since riding 21's just sucks). 25's are still plenty fast, particularly in low wind or really high wind. The difference between 23 and 25 is small enough that I'd personally pick 25's for the rolling resistance and comfort.

one thing to go along with what VN is saying, is that some tires will work drastically different in the system. Generally, Conti and Zipp tires test better aerodynamically than say Veloflex or Vittoria because Conti and ZIpp have a better transition from tread to sidewall and a slightly less "rounded" and more leading edge shape.

Bontrager has an old graph on this, essentially demonstrating the interaction between rolling resistance and aerodynamics of tires.
