    Seatposts

    So the other night I was riding with my best friend when my seat decided to go nose up without warning. Needless to say I said, "woo woo WTF?!" I got off and tightened the 1 bolt. Got back on and the seat still wobbles something terrible. I pulled the seat off the post today and as you can see in the picture it's pretty much shot.

    Does anyone have any suggestions on a good post that holds up under big weight? (385 lbs)

    Thomson. Lovely workmanship. Expensive, though.

    2 bolts systems works flawlessly, 1 bolts are always iffy. Thomson would also get my vote.

    IF in doubt abut a seatpost, just get a Thomson. Will probably outlast the rest of the bike, and should have a good resale value if you change frame and it doesn't fit later.

    This might work if you use a 25.4 mm. item 160883897625.

    The seatpast I think you have will strip out even at 159 lbs if not tightened properly. Done that.

    Go two-bolt, as others have said.

    I have had good luck with the fsa seatpost a little less expensive than thomson, but thomson is the gold standard.

    I own both an FSA 2-bolt seatpost and a Thomson Elite seatpost. The clamp on my FSA post has heavy knurling, which limits adjustments to some degree. That makes adjusting the seat angle on the FSA a more fiddly process. The Thomson clamp, on the other hand, is infinitely adjustable. The FSA post works well, once you get the seat adjusted, but I'd rate the Thomson as being better. Whether it's good enough to justify the price is an open question... for me it was.

    If you want something with setback, nitto makes some 2-bolt posts.

    Another Thomson owner. There are others out there. But, Thomsons definately get the job done.

    Agreed, two bolt designs allow infinite adjustment of seat angle and don't need to be cranked down really hard to avoid movement. I use a $35 Nashbar carbon fiber post with 2 bolts that I love (just wish they made one with setback.)

    I've got a snazzy Thomson Masterpiece and an Easton EA30. I might be able to tell the weight difference between the two if they were bare on a table. Once they're on the bike, the only difference is people look at the Masterpiece and say "nice post!" and point to a matching one on their bike. People see the Easton post in front of them on the CX course and get sad because they're getting beat by the guy with a $25 seatpost and pink wheels.

    Not sure whether it's a factor, but Thomson has a nice finish, with tightly space ridges on the post. Compared to other posts I've owned, it never, ever slips.

    The setback version, though, has a clear bend in it. Some folks love it (as I do), but others can't get used to the look. Photo on bike below...

    In at 355 lbs riding a layback seat post that I had custom made of 7/8" sold stainless steel bar stock.

    I'd guess the frame will break before the seat post gives any!!!

    I replaced my suspension seat post with http://www.amazon.com/gp/product/B00...ls_o04_s00_i00
    seems to be working just fine.

    No way you would ever damage a Thomson unless you did something really crazy.
