I see that most of touring bikes uses rim brakes and I can't imagine how you guys handled your bike when you have to roll down on your loaded bike the long descending road. Would some of you that ever experienced this conditions share your knowledge on how to brake your bike during long descending.? I'm talking about (maybe) tens of kilometers you have to roll down on your loaded bike from top of the hill you just passed. This kind of descending will wear out our brakes and rims almost instantly and lead ourselves to accident or bike troubles at minimum if we don't know how to do it but eventually we must descend that road anyway. Pls share your experience and knowledge here they will be very useful to newbees I bet.
