For 2011, Fixie Inc has gone disc-brake-only with their Pure Blood cyclocross bike, and made a few changes to drop weight in the frame and fork over the 2010 model.
Visually, the biggest change (other than the bright yellow color) is the movement of the rear caliper to the inside of the triangle, mounting it on the chainstay rather than the seatstay. Cable routing now runs under the downtube with full length housing to the brakes, which runs through the fork and chainstay tubes.
Component spec is SRAM Force’s black groupset and blacked out parts throughout. Frame material is custom drawn 4130 steel and a steel DiscO fork.
