Yeah few guys have them on the WC circuit, Sam hill, Danny heartCorrect me if I'm wrong but I'm fairly sure a few riders on the WC circuit have been running 650b ultimate's (Sam Hill?).
Either way one would expect Mavic to have released them by now
Mavic won't sell to ding bats so your out of luck peal backYeah few guys have them on the WC circuit, Sam hill, Danny heart
So I'm sure they will release in 650b soon hopefully
