Thanks to the Glasgow taxi driver and two random passers by who stopped to see if I was ok following my rather spectacular crash this evening (chain snapped just as I was moving away from a junction). No serious damage to bike or rider although my hip and shin are definitely a little discombobulated. Consolation prize is my jacket contains zero holes despite a sudden impact on Argyle Street tarmac.
There was me feeling pleased at having spotlessly cleaned the drivetrain yesterday (active ingredient 'Nitric Acid' maybe?)..
