Hill has run CB pedals since they came out in '06 and Rennie has never used them because he was sponsored by Funn and, most recently, Burgtec. oster_oops:with the new [normal, non fancy] pins, they actually work fine with 510 shoes.
of course they are better options out there, but doubt it will hold him back. unlike when they had those **** pins, and hill, rennie were still using cullys even tho they were sponsored by CB.
with real pins they are fine. not the best option, but certainly good enough.
