Shimano CS-HG51-8 Cassette Sprocket 8 Speed 11-32T (Chrome)

he Shimano Acera CS-HG41 8-speed cassette has a computer designed tooth configuration with contoured shift gates, combined with close ratio gearing which allows a more efficient use of energy through finer cadence control, the result is a very crisp, smooth shifter even when under load. Finer cut to reduce weight without compromising rigidity whilst nickel-plate finished offers hard wearing resistance to corrosion.
