The cadence meter. Went on the blink but seems to be back. I think I’d kicked it by accident when uncleating. The heart rate monitor has run out of battery but even if I could find a replacement, it requires a tiny screwdriver

Mudguards
They must feel a bit unloved as they get a kick almost every time I uncleat and the weather has been reasonably good. To install this bracket to hold the rear mudguard properly away from the tyre requires pliers. I’ve been carrying the bracket around expecting to have to sort it out in a bike shop but actually, after a week’s worth of squeeling, the mudguards have settled into a good place.

Derailleurs. Have worked perfectly so far. I’ve been oiling the chain regularly but it needs a deep clean

Pannier rack. The last time (/first time) I tried cycle touring the bars holding the rack to the frame were not shaped correctly and the rack fell off at Westferry Circus.

The falling rack broke the derailleur off. This is held on to the frame by a derailleur hanger, a weak piece of metal designed to sacrifice itself in an accident to protect the more complicated rear derailleur. Sounds like a good idea but almost every bike requires a different design and so it’s often easier to replace the derailleur. Having learned my lesson, I now carry two spares around with me.
