The cornerstone of SRAM's WiFli (Wider range of gears, Faster shifts, Lighter than triples) road system, the Apex PG-1050 Cassette offers the necessary range between big and little cogs to create the mountain goat climbing and city limit sprinting gears you'll need to make the most of every ride.
Like SRAM's higher end offerings, the PG-1050 Cassette employs an aluminum spider to create an attachment for the largest cogs to save a few grams. The nickel plated cogs are all steel for long life. SRAM's Powerglide technology ensures that there are ramps and teeth designed to pickup and release your chain for quick flawless shifts everytime. When you want to grab another gear, DoubleTap and you'll have it.
