Can I safely cut a carbon seatpost??? Need a answer quick
Moderator: robbosmans
I found an awesome deal on a carbon seatpost but its 400mm long and I only need it to be about 230 to 240mm. Can I safely cut it down to that length. Its already alot lighter than my current at 400mm but this is weight weenies. I need a quick answer.

I've done it ... no problem. I know some I've heard it's not adviseable (edge/enve? - can't remember)
Just remember to measure the minimum insertion amount and cut down from the seatpost collar mark leaving that much room. I saved about 15g off a 270mm post...
good luck, it seems intimidating, but it's not that bad once you get into it.

Check minimum length marking, make sure when you cut that you leave same minimum in frame.
Best to use a carbon specific blade, or get your LBS to cut it for you.
Seems like most WW's cut seatposts to reduce unnecessary weight.
I went from 197 to 160g on my Enve seatpost saving 37g

The seatpost needs to extend past the bottom of the toptube. Other than that, you'll be fine.
Either use a carbon fiber cutting blade or a new 32tpi blade. You can also wrap the post in masking tape to avoid splintering

I had to cut my girlfriends post on her carbon synapse to get the seat height low enough. I used a light cut-off wheel on a dremel and followed a guide line of some tape that i used to keep it even. It cut through it like butter. I wouldn't hesitate to cut another seatpost. Do the math on the minimum amount and wear a mask - i wish i would have, the dust gets everywhere and can't be good for you.
