Let's share some unpleasant mechanical failures we've had

Warm up on the trainer for the State TT Title (20k)
Speedplay Pedal came apart… lots of swearing dam near threw the bike. Wife told me jam it on and ride anyway we are here.

Got on the bike, jammed my foot in, focused on my left leg pedalling. Finished with a Silver. Sometimes you have to put it all behind you and get on with it.
