This is sort of off the back of Tamir's recent thread, but also a general question having had a broken spoke cut a ride short a couple months ago. Fortunately that was in the middle of tokyo so finding a bike shop was pretty easy/transportation home easy. So for things going wrong with the bike, is it good practice to always carry a bag with you, such that you can either take a train (or hopefully be able to get a ride/take a taxi to some station)? Any other recovery options? I don't suppose roadside assistance for vehicles/motorcycles applies to bicycles.... ?
