Well thanks to everybody who replied to my question. I finally picked the post up today and managed to get a short ride in on it. My initial impressions are pretty good once I sorted out which elastomer to use and the preload tension. Very smooth. I might try this thing on the tour bike as it's pretty comfortable. Luckly as both take a 27.2 post. I traded an old Giant MTN bike frame for it. The piece is heavy but comfortable. Cant wait to hit some trails with it.
