    Std 34.9 clamp will be fine! Just tighten it up some more. Pretty much all spesh bikes these days use that size.
    (Im using a L35 seatclamp off a Spesh on my Marin and they both use 30.9mm seatposts)

    has it got the size on the side… mine is 31.8 size (hope model)…. have you got the correct size seatpost…. if it keeps slipping down ?…
    my specialized bike has a thicker seatpost than my orange bike… 31.6 for specialized and 27.2 for orange…

    34.9mm. As I found out – wrong size for my Trek! I now have a unused 34.9mm Thomson clamp sitting on my desk waiting for me to get round to ebaying it!

    I have a Specialized Rockhopper and I broke the seat post clamp bolt.
    Does anyone know the clamp size.

    Underneath it says L35 so does that mean its a 35mm size or could it be a 34.9mm

    I have a problem with the post as it keeps slipping back down the tube….grrrrr !!!!!

    You should have a look on the classifieds, picked one up the other week for £5, pretty much as new too.
