I’ve learned that ‘mountain bikers’ don’t see themselves as cyclists, that wearing lycra somehow equates to sex with men, that bikes made in sheds are far better than bikes made in factories, that bunny hops cannot be done without flat pedals, that single speed bikes are faster than any other form of two wheeled transport, that an inch of polystyrene will always save your life, that it is essential to change your tyres between the seasons or you will die, that the ability to run tubeless tyres at 20 psi is actually an advantage, that trail centre riding is as nothing when compared to the actual wilderness riding so common on this isle, and assorted other rubbish.
Oh, I liked the one about ziptying your brake levers overnight. 😈
