When it comes to adventurous riding, a wider gear range is often better. With 9 speed and a large range, the ADVENT cassette has the low gears you need to get up and the high gears to get back down. The steps between gears are optimised to give an even spread in gear ratios, reducing the need for double-shifting to find the right gear.Key FeaturesCompatible with standard HG cassette hub bodiesContinuously molded sprockets achieve a high standard of durability and straightnessHardened steel sprockets suitable for e-bike usageSpecificationsGroup: ADVENTSpeed: 9 SpeedSurface Finish: ED BlackCombination 11-38T: 11-13-15-18-21-24-28-32-38Combination 11-42T: 11-13-15-18-21-24-28-34-42Combination 11-46T: 11-13-15-18-21-24-30-37-46Spider: NoCog Material: SteelHub Compatibility: Standard HG FreehubmicroSHIFT/Ison Part NumbersCS-H093 - CSMSH9138 - 11-38TCS-H093 - CSMSH9142 - 11-42TCS-H093 - CSMSH9146 - 11-46T
