X-Cog for SRAM XX1/X01

Instead of chalking that $400 cassette you got last year up as a loss after wearing it out quicker than you anticipated, pick up the OneUp Components X-Cog for SRAM XX1/X01 to get rolling again without handing over a hefty amount of cash. Made from tough, lightweight 7075-T6 aluminum, the X-Cog extends the life and range of your 10-42T cassette by replacing the worn out aluminum 42T. And the X-Cog delivers more range, not just an easier granny gear, which is a must for serious riders who are looking to maximize their chainring size for time trials but also want to conserve energy on grueling climbs. Its press fit design guarantees an easy, hassle-free assembly, while the full spline width prevents gouging damage to the freehub.
