The new Shimano 11-speed XT group borrows a huge swatch of technology from last year's updates to the top-end XTR line, resulting in a component group that closely mirrors its more expensive sibling and offers a more affordable option for those of us on a budget. The XT M8000 Crankset keeps the gears turning with advanced Hollowtech II construction and chain management features to keep you on track and zooming down the trail. While Shimano's bearings have always been solid, the M8000 gets an update with smaller bearings and improved seals for an even smoother ride that efficiently transfers power into forward motion. The Hollowtech II cold-forging process results in crankarms that are both stiffer and lighter than most solid crankarms, and they install in a flash with a thru-axle and pinch bolt design. The M8000 chainrings bring some additional chain-retention features to the table to make this crankset hum, including Dynamic Chain Engagement (DCE) design, a special tooth shape that results in a claimed 150% better chain retention than standard chainring teeth. The DCE tooth shape is a signature squared-off and slightly hooked profile that grabs the chain when it needs to, and lets it slide by at the back end of the pedal stroke for smooth power over any terrain. The XT M8000 1x Crankset is available with several chainring size options, allowing riders to maximize the trail ride experience based on their specific gearing needs.
