The SRAM PG-720 7-Speed Cassette features a compact design for ripping blistering downhill laps, but without the sticker shock you're accustomed to. As the most affordable 1x downhill cassette on the market, this 11-25 tooth cassette emphasizes robust strength and smooth-shifting over the lightweight construction of its X01 brethren. Tight gear steps and fewer cogs improve shifting speed as you transition from low to high gears. Extra rear wheel clearance prevents your spokes from eating the rear derailleur and prematurely ending your downhill race or afternoon of gravity-assisted fun. Bringing relief to riders without the newest setup, the PG-720 integrates with a splined freehub body found on 10-speed hubs. Also, it's fully compatible with SRAM's top-flight X01 drivetrain for riders worried about future compatibility issues. Pair it with SRAM's PC-1130 chain for the smoothest possible shifting on your downhill rig.
