Thanks

I think it goes off how many front chainrings you got.

Whats your full setup and whats the derraileur you're loking at? compatability can be found on manufacturer instructions on websites.

single ring up front (36-38t) and shimano deore cassette (12-36t) shimano XT shifters and rear mech

Your cassette can not have a 36t rear cog.

If you're running a single ring up front then a medium mech will work just fine.
Rule of thumb:
Single ring - Short cage
Twin ring - Medium
Three - Long

However this is not always 100% correct, it all depends on what tooth range you're running over. My Meta has 3 up front, but works just fine with a medium mech.

Why not, it may be a 29er?
