Seatpost advice

Postby mickisup » Mon Oct 08, 2012 20:07 pm

Have bought a 43" bike for one of my kids and its every so slightly too big. The saddle is an inch too high and if I could insert the seatpost right to bottom of the tube it would be perfect, reach and stand-over are fine but they are on tiptoes when on the saddle. Its a carbon stem and hence I am bit worried about cutting it so just wondered whether I have any option or do I have reach for the hacksaw - although slightly worried about cutting carbon and any risks? Does anywhere sell a very short post that would do a job for a few months?

You get special blades for cutting carbon, but I'll bet a bike shop would do it for a few quid if you're worried.

Cheers, that was actually what I was thinking, will try the LBS tomorrow and see they will do. Bit worried about cutting through carbon given warnings I have read.

You can cut it with a decent hacksaw (normal blade for cutting metal). You can wrap some tape round to give better purchase for the start.

Best if you can grip it in a vice (carefully ofcourse) for a nice firm base.

You just need to take it slowly when nearing the end and take of the burrs with some wet and dry.

If you are cutting it yourself, I use an old stem to clamp onto the steerer tube (or in your case, post) and use that as a saw guide.
