    So it seems - but my other bike, also a PX with the exact same BB, has done well over 10,000 miles, quite a lot of them in the Scottish rain, and has no problems. I would just put it down as a YMMV thing if it wasn't for the complete lack of noise and resistance from the BB in question.

    Starting to think that the problem might have been that it wasn't tight enough and worked loose - I have had trouble with seized pedals before, so whenever I've put pedals on recently I've used plenty of grease and not overdone the tightening. So I guess underdoing the tightening must be it.
    New crankset and pedals now on their way as they were getting on a bit, I'll consider the helicoil thing & reconditioning for next time.

    Oh, and a special prize to keezx for the least helpful post of the thread.

    This. Not tight enough. The pedal/crank interface isn't a great design. It should be like modern car wheel nuts really where the contact has a tapered conical face.

    OK - so it turns out there's a little shim sort of thing goes over the axle on the drive side... it was still sitting on the old cranks which fortunately I didn't throw out. Not sure why I couldn't find a new one on either the new BB or crankset... anyway, job done. And maybe Dennis was right...

    PS: any significance in the fact that the BB manual is first in SRAM's service page quick links?
