• Speed-clean-repack of the old bb in record time last night.
    Skills! Not squeaking now! Yay! What could go wrong! 12 miles from work!
    Morning Mr Mower Repair Man, couldn't borrow a 15mm socket could I? Need to fix my crank arm back on...
    Checking crank bolts are tight/0

  • Been there. Also had the fun experience of wondering why my single speed conversion had suddenly become noisy a few weeks back. Looked down and the chain seemed to be oscillating left and right. Stopped and realised the bb had begun to unscrew itself. Needless to say I decided not to mash it up College road in that state.

  • I've had that - my track bike's Belgian and the BB threads are clockwise on both sides. had a BB shell unscrew itself into the crank and seize the drivetrain while i was coming off a roundabout. I've no idea how I didn't end up on the floor.
