- Compatible with 7,8, or 9-speed cassettes.
- Eleven-tooth pulleys have low-friction sintered alloy bushings.
- Maximum sprocket capacity is 27T.
- Minimum sprocket capacity is 11T.
- Total capacity is 31T.
The maximum number of teeth difference between the smallest and largest chainrings (front derailleur) or cogs (rear derailleur).
One-way friction clutch that increases chain tension, reduces chain and cage movement, and reduces dropped chains. Releases for wheel removal.
