Shimano 11-speed cassette CS-HG800-11 - for Gravel, MTB and Road

The Shimano 11-speed cassette CS-HG800-11 fits MTB and Road freehub bodies equally - the 1.85 mm spacer required for Road 11-speed is included - and is therefore perfect for Gravel riders or riders who like to switch between terrains.

The HG-EV cassette is used for gradation and cadence management adapted to the rider. Shimano offers the optimum gear ratio for 11-speed shifting systems. You can

choose wider or narrower gear ratios to meet the respective requirements. With the HG-EV cassette you get an 11-speed shifting system without compromises in robustness and improved Hyperglide shifting function.
