    What size clamp for seatpost????

    Mine is 30.9. I dont see a 30.9 clamp listed....I see 28.6...31.8....34.9...

    Which do I get?? Or do i need to find a 30.9? I liked the Hope Quick Release and was going to get that.

    30.9 is the size of the actual seatpost most likely. You need to know the diameter of the actual bike frame.

    40mm top tube ovalized to 45mm at head tube, 35mm seat tube, massive D-shaped 28.6 seatstays & 31.8 chainstays with support strut.

    Im assuming its 35mm??

    Also...I am buying a stem...Mazzochi dirt jumpers are 1 1/8"????

    what sure your stem is the right size for your bars too
    25.4 or 31.8
    if you get a 31.8 or whatever and your bars are to small for it you can buy a shim
