• Swapped your cranks? I had a set of old/second-hand cranks that was prematurely killing fresh BBs.

  • Good point, but the cranks seemed fine according to the mechanic who did the job. I wash my road bike after every ride in winter (Danish roads are gritted, so you kind of have to) so bearings have a hard life, but I'm still not massively impressed by BB86. It's currently on Token bearings that seem to be much more durable than the Shimano stuff that was on there before though.

  • The crank in mine look fine as well but it only takes a little bit of uneven wear on the bearing surfaces or maybe an imperceptible bend in the axle to throw a spanner in the bearings.
