Having recently purchased an old (but rehabbed) Cinelli, I have two questions for one and all. (1)Is there any current source for the three piece seat bolt? I have been known to be hard on these being (ahem)somewhat large. AND (2) To tighten the lug to lock in the seatpost are you supposed to tighten each allen on each side equally against the center sleeve as the design seems to imply? thanks from Patrick Lay ( in 100 degree, 90 pecent humidity hiding in the house in) Chicago
