I've been running this brake on the rear for two seasons now including for commuting. I think it's a great un-sung brake and for the price an incredible stopper. Actually I know folks with fore- and aft applications - but I think it might stop *too* well for a front brake on a CX bike. I have the silver Tektro perpendiculars up front. Great brake for $35 - you will be happy with it but maybe too grabby for the front. CX set-up: '09 C-dale CX9 with Easton fork.
