A mate of mine has offered me a SRAM X9 rear mech. What should i be looking for when buying second hand? How can i tell if it is 8 or 9 speed? Will it be an easy replacement for my current X7? Its a short cage version and my X7 is a medium cage, will it make any difference? Ive got so many questions......please help!!!! :oops: :?
