Does anybody know the best saw to trim a Carbon/Kevlar Windcheetah seat?
It needs to lose some material around the shoulder area, to make it the same as my carbon seat.
Thanks

  • What you need is a tungsten carbide cobalt blade. They're usually round and are used to cut tiles. Fit it to your trusty hacksaw and go slowly. Finish off with 320 & 600 grit emery paper.

    Now before I go any further, what normally happens at this point is that some clown comes along and advises you can cut carbon fiber perfectly well with a normal hacksaw blade "so long as its new". They then go on to say that's what Easton recommends, so it must be the best thing. Then a great 10-page debate ensues about carbon fraying, microcracking, formation of defects & stress concentration points, etc.

    Suggest that you apply tape to either surface to be cut to keep stray fibres to a minimum - you can also mark your cut more cleanly. When cutting composities, sometimes its useful to score the surface along the cut line with a sharp blade - it minimises damage to the fibres on the top surface from by the action of the saw.
    Make mine an Italian, with Campagnolo on the side..

    Thanks for the info.
  • OR, you could just buy a dedicated blade/file/cutting implement for carbon. They do exist you know. Shame most shops dont know they exist, as Ive seen some fking shocking steerers from supposed "excellent shops" in my time!

    Dont be breathing in the fibres either, they are none too good for your wellbeing
