Cutting a carbon seatpost?

Is there any reason not to? Ive bought a new odd diameter WR post from Italy and its longer than it needs to be by 80mm (I specced the length but it's Italy). The post has a nice beveled finish at the bottom which I would lose, but I would sand the raw edges. I have a saw guide and fine saw blade for steerers that I could use for the job.

Oh yeah – apart from the extra weight is there any harm in having loads of post inside the frame?Pegoretti

No reason at all, its quite common on Tri/TT fames with an integrated seat post.Pain hurts much less if its topped off with beating your mates to top of a climb.0

Well TBF it rather depends on your definition/understanding of 'has no use'.
Some people may think they can cut it down to within a few cm of the insertion point, whereas the likes of you and I obviously know that there is a minimum safe insertion length.
So yes it may seem a daft question but not everyone knows what we do.Yellow is the new Black.0 -

Brilliant. Man who can't decide whether to cut down useless carbon tube that he doesn't need gets angry shocker.
Sheeeeesh, next thing we know he'll be asking whether he needs to cut the excess off his new cables. Noooo - don't do it. Yes, do it!
There, that's messed with your level of general incompetence ........ You're going to be up all night with that little conundrum .......0 -

Lets ask Cleat.
Surely it would make more sense to cut down the seat tube, and leave the seat post at its original length.0 -
There's no reason you can't cut your seat post down.
All you need to do is check on the seat post and measure the "Minimum Insertion" and make sure that if you cut any off, you will still have that much seat post inside the frame.
Also, check with the manufacturer to see if they quote a "Minimum Insertion" for the frame (if your using a different post than what came stock) and go with the biggest of the two.
There's nothing wrong with saving a few grams (not that it will make too much difference) as long as you do things safely.
Also, use the proper tools or get a decent bike shop to do it.0 -
Probably only worth it if the seatpost reaches the bottom bracket. Or you're using lead piping so cutting off a few inches will save a few pounds of weight. Cutting 2" isn't going to save so much weight you'll notice it during riding.Say... That's a nice bike..
