Yo Dennis, this is my first fixie put together with the help Sky, Anthony and all the radical guys of velo culture bike shop in la Jolla, california. HE, Leroy, a centurion frame and rides like a dream. I don't know the specifics on the parts but I added my own touch with some fluorescent spoke beads. boo ya. To my first of many fixies and to this amazing website! cheers! -Emily, San Diego/Davis
