Close ratio gearing allows a more efficient use of energy through finer cadence control
Six 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
Chrome-plated finish offers hard wearing resistance to corrosion
