25.4 quill, 135mm c/c, this is the alloy head version without the plastic fill in cap peice on the top, so must be a slightly later on, NOT the horrendous steel shaft jobbie. Red elastomer, v.good cond. but not new. Shall we say £20 posted uk
Hi, its got 25.4 stamped on the quill, just checked the forks with an aheadset stem thats 1 1/8" and its spot on. Whether 1 1/8" = 1.125" not sure how good is your maths. :roll:
