Found a slit in the sidewall of my tyre, with the inner tube exposed when under pressure. New tyre now fitted. Abi found a huge thorn through the tread of her Cyclocross tyres.
that will teach you for doing so much biking and wearing your tires out! Abi - can't do much about a thorn, but to avoid hedge strimmings
3 rear tyres, 3 bottom brackets, 2 sets of brake blocks, 2 gear cables, 1 set of jockey wheels, and 50% wear on the rim of my rear wheel. It is easier looking after running shoes - throw them out when worn out and buy new ones.
