Shimano 105 5800 11 Speed Road Cassette

New high performance 11 speed cassette with Hyperglide EV sprockets with contoured shift gates, resulting in a precise shift even under load.
The close ratio of 11 speed gearing allows a more efficient use of energy through finer cadence control.

The largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity as well as this, all sprockets are cut away and drilled to further reduce weight without reducing rigidity.

Nickel-plated finish offers hard wearing resistance to corrosion.

Range:    11-28T
