1. Short cut through the ferry that ended up with me tearing the bike off the rack, snapping the roofrail and denting the roof BIG time. Arrived in Morzine later that day. It was my youngest son’s bike with a 7 speed cassette. You try and get a replacement wheel in DH central at short notice.
2. Tried to bend the mech back into place. Snaped an XTR mech. Mind you, for some reason the nice on-line bike bits shop might have sent me an extra one 🙂
3. Alcohol lubricated late night maintenance has killed my DT Swiss rear hub 🙁
4. If you reverse your car over your rolf wheel the hub cant be fixed with a blowlamp.
5. Microbore central heating piping makes very poor bushes.
FWIW I have learnt from each and every mistake. So have my friends- they avoid my maintenance.
