Fits 1" threaded steerer. 31.8mm handlebar clamp. 80mm extension. 225mm quill (same length as Nitto Tallux). Almost like new. I inserted it in the steerer of my Hillborne to just beyond the min insertion line and tightened the quill bolt, so there are two very slight lines visible on the quill just above the min insertion line.
Includes the VO cloth bag.
