Hey carbon,i looked at the pic of your 857 and i am almost certain taht my frame is a 857. carbon does the 857 come with the rear nr-2 shock?because mine is missing the shock assembly.Did the 857 line come out before the 3000?where can i find a spec sheet on this bike?i'll try to get a pic up later this week
