Guaranteed to stand up to all the abuse of tough trail riding, the corrosion-resistant chrome-plated sprockets on this XT M770 cassette give you reliable power delivery and clean, swift gear shifts. It also benefits from Shimano’s Hyperglide technology, which optimises the sprocket's teeth and adds contoured shift gates to speed up the gear changes. Shimano also carefully chose a close gearing ratio to make your pedalling cadence smoother. This ensures even power delivery to get you up to speed and up steep climbs more efficiently.
