The SRAM 'PowerGlide' shifting experience is well-known in the cycling world today, as it should be. The crisp, positive, and reliable shifting that results from the PG cassettes have resulted in many converts to SRAM's smooth design platform. From its Apex group on up through Red, SRAM's leading technologies continue to drive the industry forward, and its latest cassette iterations are helping to lead the charge. SRAM's PG-1050 stands as the cornerstone of its WiFli (Wider range of gears, Faster shifts, Lighter than triples) road system. The cassette provides 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. With SRAM now implementing the 11-36 and 12-36 options, you'll be covered for almost any roads imaginable. Like SRAM's higher end offerings, the PG-1050 Cassette employs an aluminum spider to create an attachment for the largest cogs in order to save a few grams. The nickel-plated cogs are all steel for long life, and the cassette comes in at a reasonable 250g (11-23T) and 299g (11-32T), respectively. SRAM's PowerGlide technology ensures that there are ramps and teeth designed to pickup and release your chain for quick flawless shifts every time. The PG-1050 is available in several ratios. Its spline configuration allows it to fit on any Shimano 9/10-speed freehub, and it's compatible with any 10-speed chain: SRAM, Shimano, or Wippermann's S-series chains. What SRAM suggests, of course, is that you use one of their 10-speed PC-1000 series chains for optimal shifting. Includes a forged, anodized, and laser-etched lockring.
