No way will a road rear mech work - they top out about 27T max rear cog. You need a Shimano Shadow rear mech (apparently - haven't tried this myself). It's the max cog size that will limit you, not the cage length. HTH.

You'll need a med or long cage mtb mech, I doubt any road mech will take a 36t sprocket.
