XMR Rear Hub

Description The White Industries XMR Rear Hub is a lightweight, precision-machined 6-bolt disc rear hub built for mountain, gravel, road, and touring bikes. We machine, assemble, and inspect every hub in our Petaluma, California facility. As a result, the XMR delivers smooth performance, lasting durability, and premium American craftsmanship. The XMR traces its heritage back to the original White Industries Ti Cassette Hub introduced in 1992. For more than 30 years, we’ve refined our hub designs through real-world testing and continuous innovation. Today, every XMR carries the same proven DNA: simple engineering, dependable performance, and long-lasting reliability. The XMR uses the industry-standard ISO 6-bolt disc rotor interface. Therefore, it delivers dependable braking performance in every riding condition. Its rugged construction makes it an excellent choice for mountain biking and loaded touring. Meanwhile, its low weight and classic high-flange design also make it ideal for gravel bikes and performance road builds. At the heart of the XMR are four premium Enduro sealed cartridge bearings. Two bearings support the 6061-T6 aluminum hub shell, while two more support the 6Al-4V titanium freehub body. Together, they provide smooth rolling performance, efficient power transfer, and exceptional long-term durability. Choose from six spoke drilling options, five colors, two axle configurations, and five freehub body options. With lots of  possible combinations, it’s easy to build a custom wheel set that matches your bike, drivetrain, and riding style. Whether you’re riding technical trails, exploring gravel roads, or touring long distances, the XMR delivers premium Made in the USA performance built to last.
