Haha, i love all the bitchiness about ACS freewheels, they are the shizz man, i'm running one on my stock, i stuck it on the rear though i did, 16tooth one, running 18:16, as mr ailsbury said, clean them out and shit and they'll be fine. Well, i built this wheel years and years ago and its still working completly fine. Don't think it's ever skipped on me.
