Hell, Mavic doesn't even list the Io on its
own page of TT wheels:
https://shop.mavic.com/en-us/road-an...on/wheels.html
If that doesn't make my point, I don't know what will.
"But, the the reason the Io isn't offered as a road TT wheel is because it doesn't have a brake track!"
lol...they sell the Io for $4,000 USD. You think they are technically incapable of adding a brake track for that kind of money?? Pfffft. They know that the TT crowd would laugh them off of the scene if they did so. So, they just milk the trackies.
(for the record, I've owned the older Io & Comete and 2 sets of front/rear 808s and 900 disc)
