• Have an Athena carbon power torque crank, fitted to an Italian bb Battaglin.

    Will remove for winter strip down. I have removed veloce using a puller lots of times, but not a carbon model.

    Park Tool kit has a plastic sleeved puller that just explodes, plus it will not fit between the cups and crank arm on Italian bb.

    Videos show the use of the puller with a cardboard insert behind to prevent damage … given they are torqued up to 40 odd nm, inevitably the carbon cracks.

    I have seen a cyclus tool which allegedly goes between the cups and arm for carbon cranks, but as stated the plastic Park equivalent I have will not fit between the gap.

    Any advise from somebody that has done this without damage, would be appreciated.
