Short, medium and large refer to sixe of the derailleur cage that accomodates a certain size of cassette experts migh correct this guess a short cage accomodates a 11-23, a medium 12-28 and a large 34t cassettes. You won't want one that too small for your current cassette size. I never toured but I guess some folk would like a lowered gear bike for touring and hence would want a larger cassette and hence would need a larger cage.I want to substitute a 9-speed Deore LX rear derailleur for a second-hand ebay 9-speed XT derailleur. I've noticed that derailleurs can be short, medium and long cage. What does this mean? What's the most suitable one for touring?
