If you've been spending every ride lamenting your lack of "just one more" gear in either direction, give your ride buddies' ears a break and take a look at the SRAM GX XG-1150 11-Speed Cassette. Constructed with a whopping 10-42t gear range, you'll be hard pressed to find a time when you're praying for a miracle gear on the trails, and you won't have to drain an entire season's upgrade budget to get it. In fact, SRAM uses a remarkably similar design for the XG-1150 as it does on its top-end X1 cassette, shaped to clear mud when you're trudging through the deep stuff and function consistently through whatever conditions the day throws at you. Send away and know that 123 stainless steel pins will hold the 11 chromoly steel cogs together through big hits and the occasional spill.
