Had real problems with the seatpost slipping on my fuel at 10 under on Saturday. It was dropping about an inch a lap, i even had to stop mid-lap to raise it again. Only had the bike a few months and suspected it was slipping slightly but the bike has been in and out of the car a few times and the post heights been reset, so I couldn't be sure. Anyone else had any issues? The qr clamp is tight up to the point the plastic bushing is wearing. I'm trying carbon grip paste I have for the road bike bits as a last resort, as I don't have time to take it back to the dealers I got it from anytime soon. Shouldn't really need to do this on a new bike, would it be reasonable to ask for a replacement seatpost or is it more of a frame issue?
