I did a quick search and didn't see anything that looked like a match so here's my question. I'm looking for a seatpost for an '01 Gary Fisher MTB. The Bontrager post on it now has a single bolt and yesterday while on the trail it rotated when my fat ***** when over a big bump. (Guess I need to learn to get off the seat, eh?). I'm thinking a 2 bolt setup such as the Easton Ea70 would be the way to go. Thanks in advance for your recommendations.
