Mustang: grey damp and no wind

Pushed back the ride to get some maintenance done. The Zing has a new chain that I failed to fit. Shimano chains have a single-use pin to close the chain. I broke it. The Jake also has a new KMC chain which was easy to fit but there’s a problem. The cassette is worn out on about 4 cogs. It’s the original on a 2015 bike, so that’s a decent life. The jockey wheels were almost toothless. Changed them too.

Great, an hour’s work and now 2 bikes are unrideable. At least I got a run this morning.
