tried it the other way but A. didn't like the look and B. it would pinch the frame tube to tighten it that much so was not the correct size post.

so you can get 22.6 then ???

Post by: HUTCHMAN on June 29, 2010, 07:07 PM: i think it was something like 22.6(it was a Hutch Hi-caliber post that would'nt fit ANY Hutch frames i've got)and you could see the slight taper where the seat guts clamped on,so the majority of the post was obviously larger diameter.

Post by: pickle on July 08, 2010, 08:32 AM: i have gone down the pepsi can shim road for the moment, but i also have a TNT twin bolt clamp on the way over from the states so should be better for clamping with the reversed slot style seat tube :daumenhoch:
