A go-to cassette for any off-road and gravel riders looking for lightweight performance. The cassette uses Shimano's Hyperglide technology, with sprockets that have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load, whilst the close-ratio gearing enables more efficient use of energy through finer cadence control. The light and durable sprockets on the Shimano Deore XT M8000 mountain bike & gravel cassette are cut away and drilled to further reduce weight without reducing rigidity and their chrome-plated finish offers hard wearing resistance to corrosion.
