Opinions of disk wheel covers

i tried to email itcycles about their carbon covers but got ‘failed delivery’ messages with the address provided on their site. THIS IS UNBELIEVABLE! Does this company really exist?

Last summer I tried to reach them as well and never did get an email response.

Ha! Interesting! Do you think carbon covers would be significantly lighter than PVCs? On another topic, does anybody know where one can find the whirlwind decals displayed on the zipp disc on the front page of wheelbuilder.com’s website? They look really cool!!

Let me make sure I understood this. A disc will gain you 30 seconds on a 40km. So on an Ironman 112 mile course ( about 264 km) you could expect about 3 1/2 minutes?

Whoa, whoa! 180km! Please, lets not go riding 50% further. Bike ride is long enough as it is!

My bad! Thanks for the correction. So that would make it even less of a time gain? I’ve searched on google, but haven’t come up with figures on how much faster a disc wheel is, just efficiency and drag comparisons with spoked wheels. Interesting, but the bottom line is speed, and that’s what I want to know. Any help out there?
