Shimano Deore M591/590 Front Gear
Available in both top swing and conventional swing modes.
Shimano Deore M590
The low-clamp top-swing design can be really useful on some full suspension frames where a higher clamp can't be fitted.
Shimano DeoreM591
The high-clamp conventional-swing design is reckoned to be harder wearing.

- Better clearance between tyre and the derailleur's inner chain guard compared with previous models.
- Angled clamp bolt makes it easier to fit.
