The new 10-52t, XG-1295 cassette gives riders more than ever before, with an unprecedented 520-percent range. For a little extra to avoid the hike-a-bike, a little more in the “spin to win” game, the XG-1295 cassette also allows stronger riders to increase their chainring size if they want. Also available in the 10-50t configuration!

Customer Reviews
Awesome cassette, works flawlessly . I have the same 10-52t in copper on another bike. I got the X01 instead of the XX1 for my new build to keep things low key, black and silver, without gaining any weight over the XX1 cassette. Shipping from Thunder Mountain was quick.
This cassette is SRAM X01’s latest offering in an all black colorway. Released in September 2022, it’s ultra light and has the X-Dome one piece machining construction giving it very consistent, smooth shifting all day, everyday.
