• Took a 105 Chainset out, put the new Aldhu24 chainset in a couple of cm and now it's stuck. Now want to take it out and it won't budge.

    It's all compatible on paper - just a case of tolerances? Bikeradar notes BB86 as having less stringent tolerances.
    I also didn't grease the axle, error?

    I've tried applying some WD40 in there, tapping with a mallet and it just wants to pull out the inner part of the BB (which I assume I'll have re-press now (?) but don't have the tools).

    Toying with sticking another chainset into the NDS and trying to tap it out from the other side(?).
