This old 70s or 80s Raliegh 3 speed I've recently bought has Cottered Cranks. After a 3-4 days of riding around town. the Left Crank has become a little loose.
You can just feel the play in the Crank as it swings over vertical. So what is the easiest / fastest Cheapest way to fix?
I"m in Central East London. should I just take it into a Cycle Shop? are they going to have the right equipment to fix?
Do I need to pull it out completely?
or can I just tighten it up with a wack of a hammer?
