The Shimano Deore M592 Shadow Rear Derailleur is ideal for trail or all mountain biking. This Rear mech benefits from a top normal spring design and in high gear, the derailleur has a profile that is a 15mm less than a traditional rear derailleur. The derailleur body has a stronger spring providing greater stability and the redesigned bracket axle keeps the derailleur body from contacting the chainstay.

Features:
- Top normal spring design
- Direct cable routing
- Stronger spring
- Redesigned bracket axle
- Long Cage
- SGS Black
