I have just purchased a pedalforce carbon fiber seatpost and need to cut it down. What is the best way/tool to do this? thanks

Assuming you have a good reason to do this (not to save weight!) the general recommendation is a fine bladed hack saw, and then dress the job with a fine file so you have no rough edges remaining.

See if you can get ahold of a saw blade guide from a shop, they hold the blade straight and don't let the post move making a neater cut. TTFN

Just went through this myself (but it was a carbon steerer). Two things:

1) Use a saw guide. The park one works great.

2) The "best" (and only in my opinion) blade to use (assuming you are using a hacksaw) is a carbide "grit" type. It will yield a smooth cut and will not "tear" at the carbon fibers.

agreed, use a guide, but also wrap the part you're cutting in electrical tape and cut right through the tape and post. I do this when i cut carbon ski poles, it keeps things nice and clean and smooth.
