all i want is a LINK to `easy to follow` `clear` photo step by step of REMOVING and PUTTING ON the gear cassette.
you mean crankset. well the best would be to buy a book on bicycle repair maintenance such as from rodale press( bicycling magazine). or bike repairs for dummies. go to youtube search crankset removal and bb removal for vidz. you'll need the correct tools to do it also so why not go to local bike shop and ask them for a demo and what tools are required for your bike. buy the tools and parts from your LBS (local bike shop). tools like ratchet, socket, breaker bar you can get from anywhere such as walmart, sears, hardware store.
