Shimano's flagship XTR twelve-speed cassette stretches your climbing range to a 51-tooth low gear so you can spin steep singletrack instead of grinding to a stop.

When the trail kicks up and your legs start to argue, having that extra-wide gear range in your back pocket is the difference between a clean climb and a foot-down-walk-of-shame. The XTR cassette sits at the very top of Shimano's mountain bike lineup, which means every tooth, every ramp, and every shift surface has been obsessed over by engineers who spend way too much time thinking about chain engagement angles. The result is a cassette that shifts with an almost eerie precision, whether you are sprinting out of a berm or desperately searching for easier gearing halfway up a wall of roots.

Weight matters when you are hauling yourself up thousands of feet of climbing, and this cassette has been built to shed grams without sacrificing the durability that keeps it shifting crisply after months of mud and abuse. The construction pairs harder materials where the chain hits hardest with lighter alloy where it can get away with it, so the cassette earns its place on a bike where every gram is questioned.

Compatibility is straightforward for twelve-speed XTR, XT, and SLX drivetrains, meaning you can slot this into a build or an upgrade without a parts compatibility puzzle. Pair it with a quality chain and a well-tuned rear derailleur and you will spend your rides thinking about the trail, not your drivetrain.

Why You'll Like It

Riders chasing podiums on gnarly enduro stages or long-day trail adventures get a cassette that refuses to be the weak link, delivering crisp shifts under load when fatigue is making everything harder. Gram-conscious XC racers get top-shelf Shimano engineering that earns its weight penalty back in confidence and consistency across every climb. If you have ever been mid-suffer on a steep pitch wishing you had one more easy gear, that cavernous low-end range has you covered.

Key Features

  • Extra-wide gear range including a massive low gear lets you spin steep, technical climbs instead of grinding to a halt and walking
  • Top-of-the-line XTR construction uses harder materials at high-wear contact points so the cassette keeps shifting like new long after cheaper options have gone soft
  • Precisely engineered shift ramps guide the chain from gear to gear so smoothly you can upshift or downshift mid-corner without interrupting your flow
  • Weight-optimised design sheds grams without sacrificing strength, keeping your rotating mass low so accelerations feel snappier and climbs feel a little less brutal
  • Designed specifically for twelve-speed XTR, XT, and SLX systems so it drops straight into your existing drivetrain without compatibility headaches
