Can I use a triple chainring with a 10-speed cassette? Ive seen some roadies claim its impossible, but Im not buying it - literally, Im too poor to buy into the hype. Ive got a triple chainring lying around and Im wondering if I can slap it on my mountain bike and pair it with a 10-speed cassette. I know some of you are going to say its not compatible, but Ive heard rumors of some clever folks making it work. So, can someone please enlighten me on the technicalities of this setup? Is it a recipe for disaster or a genius hack? And dont give me any of that its not meant to be nonsense - I want to know the real reason why it might or might not work.
