    Thomson setback seatpost

    Is there any advantage to a setback seatpost for a GF 29er?

    Just recently I heard of some GF owners rave about the Thomson setback seatpost.

    Does the setback position lend itself well to G2 geometry?

    Just a curiosity.

    I ride a Hifi 29er and have been battling some seat issues am thinking this might solve the problem.

    Thanks for the input

    In my case it got the clamp back on the seat rails where it belonged.

    I have a 2010 HiFi 29er deluxe. I think I need a setback post as well. Thomson's are 15 or 16mm set back, Ritchey;s are 20mm, easton is only 5mm. It is really about how you want to fit on the bike, if you want to be more over the pedals or behind the pedals, if you have a long ot short femur. Best thing is to try it out or get fit by a qualifed bike fitter.

    Have an '08 geared 'Fly, '09 SS 'Fly, and a '10 SF100 - use the Thompsen setback on all of them.

    The SF100, as a 2010, needed it the most, because it seems shorter than the earlier G2 generation. Much better descending off the back with it. Thompsen is so good I set aside the stock Bonty carbon post, just for the geometry.

    On the other 2, Tinshield is 100% right - gets the seat rails out of the backcountry.

    Since they are carbon, I got the longest - 440 - to get them deep.

    Can't say enough about the strength - pretty light too, even if Elites.
