I'd suggest a fine toothed blade, maybe even a decent junior hacksaw, and finish off with a fine wet-or-dry paper so there's no ragged edges left, Posted 8 years ago druidhMember Make sure you're wearing a good face mask. You don't want to be breathing in any carbon fibre dust Posted 8 years ago monotokpointMember Cool thanks guys. Here goes…! Posted 8 years ago monotokpointMember before I take the plunge with a hacksaw, does anyone here have a USE Carbon seat post that they have cut down. just want to check its not going to ruin it Posted 8 years ago frank4shortMember Failing that get your hands on a plumbers pipe cutters & use them. Will give you a perfect cut once you use them carefully. Posted 8 years ago trail_ratMember frank4short are you mental …. all that will do is crush the carbon…. Posted 8 years ago frank4shortMember Used mine to cut my carbon bars. Never had a problem just need to be very careful doing it. Quarter of a turn adjustment per revolution of the post works fine.
