- Close ratio gearing allows a more efficient use of energy through finer cadence control
- Largest sprockets are mounted on lightweight alloy carriers to reduce weight and increase rigidity
- Sprockets are cut away and drilled to further reduce weight without reducing rigidity
- Light and durable 40/42T sprockets
- Chrome-plated finish offers hard wearing resistance to corrosion
- Alloy cassette lockring
