Puncture repair time this morning. Find the thorn stuck in the tyre; start trying to remove it, then realise that this old, worn tyre really needs replacing. Down to the bike shop on my other bike; find it shuttered, with a notice saying that from 1st November it will be closed on Mondays.

Nothing is ever straightforward in bike maintenance.

By the way, Monday seems a particularly bad day to be closed, given that most incidents requiring kit to be replaced will have occurred at the weekend.
