i love on one and i love the ride on this frame :D , but, i just cant get the ruddy seatpost to stay up!. just wondering if anyone else out there has this frame and maybe suffering? after many other things, including trying a coke can shim which on one themselves suggested, almost ruining the frame ( and quite frankly dont think i should be having to do on a £1300 hardtail frame) i have now gone for a top of the range ea90 carbon post, carbon paste and a hope qr seatclamp, it still slips!!!!!!!!! im 11 stone btw so its not down to my fat arse!

been riding now for 20 years or so , never had this problem on any of my bikes before, its at the point where i dont want to ride it anymore.

just would like to know if anyonelse is having the same problem with this frame?

sorry to go on!!!!!!!!!!!!!

    have you had the seat tube size checked?

    Try a non-QR seatpost collar. Hope aren't always regarded as the best anyway.

    Carbon paste is a good idea, but I'd be tempted to use an alloy post so I could really crank the torque up on the seatpost collar

    you could try just wrapping paper around the seatpost until it stays up, a bit of a bodge job, but won't damage the frame/seatpost

    I have a Hope QR on a Dmr and I have to do it up FT+1 to stop the post slipping so try a different one as suggested above

    Try a Ragley seat clamp (assuming you can get one in the right size), they seem to have a good track record for slipping posts.

    My mate had the same problem on his Trek, carbon paste worked a treat and it hasn't slipped since (He's a big lad!)
