That was until I spotted Jean's destroyed tyre.
A quick Google and I was off on a 4 mile ride in search of some new rubber.
So many numbers these days for tyres! And I had to bear in mind the one currently on Jean's bike was maximum width, as the helpful assistant tried to upsell a more off road wider one.
After riding back with the tyre over my shoulder and feeling like the Michelin Man, out came the tools.
