Cutting Carbon Seat Post

[Jono Waddell]

Got a 400mm carbon post which is too long for the frame. Can i cut it to 350mm??

I can’t see why not. They cut carbon steerers every day.

[Jono Waddell]

I thought so. Just thought it best to check.

Hope the other hubbers will give you good advice, or Pm Johan Bornman I think he will know

You can do it. Just make sure you leave enough length to securely mount it.

 

You can use the same cutting method as for steerers:

Just note that, to prevent splintering, you should use a finer blade to cut carbon than you would for metal.

Use Masking tape on the area you want to cut. If you do not have a saw guide like in the park Tool method use a sheet of paper.... fold it around the seat tube. Bring the two ends together so they line up and mark it. Now you have a perfectly aligned mark around the tube. take time and patience and saw it.
