Cutting carbon seat post
#1
I am going to replace the dropper seat post on my wifes Specialized Rumour mountain bike. She wants me to fit a lighter carbon post as she does not use the dropper post. My question is I have a 400mm long post. I need to cut about 70mm off the bottom to allow it to fit into her small frame. Will this cause any issues? Seems like a good idea to me but I've broken plenty of things before.

Cheers Stevo

Yes, you can cut the carbon post. it should be done with a blade designed for carbon. It can then be finished with sand paper or emery cloth.( finer grades ). I would like to note that if she adjusts the seat often ( for different riding styles ). I do not recommend a carbon seatpost. Also the weight saving is not worth it, the are not very rugged and often way more expensive and not much lighter than a quality alloy post. They look pretty in the box thats about it. there are many other ways to "Shave weight" than a carbon seat post

Thanks for that. I hear what your saying about the carbon. She is a pretty (in all senses of the word) light weight rider and has decided after having the dropper post for a year and not using it, that an adjustable post is not required. Even an average quality alloy post will be lighter than the dropper she currently has. i'll start looking now and see whats available. Cheers Stevo
