Whats the most genius way to breathe new life into a worn-out cassette on my mountain bike, short of breaking the bank or sacrificing a limb to the bike gods? Im talking outside-the-box solutions here, people - are there any DIY wizards out there whove conjured up a magical fix involving nothing but duct tape, fairy dust, and a healthy dose of skepticism towards the replace-it-with-a-new-one crowd? Can I get away with simply flipping the cassette and running it in reverse, or is that just a recipe for disaster (and a bunch of weird looks from my fellow trail riders)? Seriously, whats the most unorthodox yet effective method for reviving a cassette thats seen better days?
