XMR+ Boost Front Hub

The White Industries XMR+ Front Hub is a lightweight, precision-machined Boost 6-bolt disc hub built for modern mountain and gravel 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 Front Hub introduced in 1992. For more than 30 years, we’ve refined our hub designs through real-world riding and continuous innovation. Today, every XMR+ carries the same proven DNA: simple engineering, dependable performance, and long-lasting reliability. Designed for Boost-spaced forks, the XMR+ uses the industry-standard ISO 6-bolt disc rotor interface. Therefore, it delivers confident braking performance for aggressive trail riding, backcountry adventures, and fast gravel routes. At the same time, its low weight, clean profile, and robust construction make it an excellent choice for riders who want strength without unnecessary weight. Two premium Enduro sealed cartridge bearings keep the XMR+ rolling smoothly mile after mile. They also reduce maintenance, allowing you to spend more time riding and less time servicing your bike. Choose from four spoke drilling options, seven anodized colors, and two axle configurations to create a custom wheelset that matches your bike and riding style. Whether you’re building a lightweight gravel bike or a capable trail bike, the XMR+ delivers premium Made in the USA performance built to last.
