Shimano Deore XT doesn't just have a following because of the value this Japanese brand offers, it's also because it's their original mountain bike groupset that has intuitive shifting, reliable braking and efficient maintenance. In the case of the XT WH-M8129 27. 5" Boost Wheel, mountain bikers can trust in the reliability of XT for superior trail performance cornering at top speed. On rough rides, you'll benefit from smooth control so you can up the confidence and kick it into gear. M8120 rims are constructed of lightweight aluminum that cuts costs and offers reliable durability and rigidity for speedy off-road raging. With the capacity to host 27. 5" tires for maximum acceleration and stability, these tubeless rims have a width of 34. 7mm and weigh in at just over 1,000g. Thanks to the combined rim's shape and hubs' wide flange profile this wheel has zero dish, and even spoke tension due to offset rims on both the drive and non-drive side. 28 double-butted, straight-pull spoked are laced to centerlock hubs for lasting strength, and the M8120 rear wheel features a lightweight aluminum Micro Spline 12-speed freehub. It's compatible with 10t top gear by Micro Spline, and the smaller spline diameter, in addition to more widely distributed splines, limits cog damage on your wheel. A centerlock design makes rotor installation quick and easy. Shimano Deore XT brings outstanding performance to any trail, and M8120 wheels are designed to tackle the tough stuff so you don't have to worry about ramping up the speed. This new generation of wheels specifically focuses on handling and reliability so you can focus on enjoying your ride. And, with a simple setup, you'll save time with maintenance so you can spend more time out on your pre-snow bucket list.
