Shimano XTR Trail Cranks M980

The DynaSys components are designed as a complete system with features made to complement each other and provide the most efficient and reliable shifting available. The XTR Triple crankset is the end result of the evolution of 6 XTR groupsets, and features all of Shimano's shifting technology in their lightest crankset yet. While many riders will flock to the in-vogue 2x10 drivetrains that are currently sweeping the market, most folks who don't race at a World Cup level will find they'll be missing a lot of the low-range gearing you get from a 3x10 setup. If you ride real mountains and can't bare the thought of having anything bigger than 24t for your smallest chainring, the XTR Trail crankset is for you.

When it comes to high performance mountain bike parts, Shimano XTR components are the best in the business. Being Shimano's flagship groupset, the XTR drivetrain features all the bells and whistles available combined with incredible engineering and superlight materials. The M980 crankset features the latest generation of Shimanos hollow crank arm technology that boosts stiffness over single-wall cranks, while actually reducing weight. A 24mm pipe billet steel axle continues the stiffness theme without needing anything proprietary and allows the XTR cranks to fit both standard threaded and press-fit bottom brackets. The M980 sealed bearing external bottom bracket is included with the cranks and next to Chris King is as good as you can get when it comes to smoothness and durability. Like the double cranks, the chainrings used on the triple are a machining work of art, with tooth profiling, double pins, ramps and guide plates that will spoil you with quick and accurate shifting.

Dyna Sys
"Shimano has been making mountain bike drivetrains for more than three decades, including eight generations of Shimano Deore XT (the original MTB drivetrain) and six generations of its flagship XTR group. Each generation is a reflection of the riding that defined the sport and the technology that defined the era. True to this legacy, our next-generation Dyna-Sys drivetrain brings with it the legendary quality, durability and performance riders expect from Shimano, all packaged to meet the ever-evolving demands of today’s riders".
