Shortening of carbon bars and carbon seat posts?

Syntace carbon bars can be shortened, but not necessarily just as you like.

Please leave enough room for grips, shift- and brake levers. If applicable, read and observe product data and/or mounting instructions.Carbon bars should be cut with a metal saw, NOT with a tube cutter such as the Syntace speed cutter.

Carefully deburr the cut ends with fine sandpaper and protect it against splintering with a clear lacquer or super glue. We recommend the use of CRB bar-end plugs, even if you don't normally use any. If necessary, use a drop of super glue to insure against the plugs falling out.

For use with bar ends, do not shorten the bar and use CRB bar-end plugs.
