Shimano Altus CS-HG20-7 Cassette

Shimano Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. Gearing gives a low sprocket making it easier to climb even the steepest of hills. Sprockets are cut away to reduce weight without reducing rigidity.

Features:

• A budget 7-speed Shimano cassette
• Hyperglide sprockets
• Works best with IG (Interactive Glide) and HG (Hyperglide) chains
• Sizes available from Manufacturer: 12-28T, 12-32T
