Dominate Trails with Uncompromising Precision: Boost Rear Hubs

Crafted for serious mountain bikers who demand relentless performance on unforgiving terrain, our Boost Rear Hubs are the cornerstone of a responsive ride. Forget flex and wasted energy – the one-piece solid axle delivers exceptional stiffness. This translates directly to sharper suspension action and maximizes every ounce of your pedaling power, propelling you forward efficiently whether you’re climbing steep technical sections or sprinting out of corners on your enduro or trail bike.

Conquer mud-splattered paths and creek crossings with confidence. Engineered for resilience against harsh elements like water, grit, and trail debris that plague aggressive off-road riding in wet conditions or dusty environments. Heavy-duty bearing seals combined with a unique threaded driveshell seal ring form an impenetrable barrier protecting critical internals from contamination that can lead to premature wear during demanding all-mountain adventures or professional MTB wheel builds.

Experience lightning-fast engagement thanks to the exclusive RingDrive™ system. With an industry-leading 72 points of contact meshing simultaneously, power transfer is instantaneous – crucial for technical climbs and explosive maneuvers where split-second reactions matter most on rocky descents or root-infested singletrack.

• Built Stronger: Canted flange design significantly boosts wheel strength for enhanced durability against impacts common in downhill racing or aggressive trail riding.
• Simplified Maintenance: Designed for real-world mechanics – service bearings easily using just a common T10 Torx driver and a simple pick or pen knife tool.
• Boost Standard Ready: Specifically engineered for compatibility with the modern Boost 148mm x 12mm thru-axle standard found on performance mountain bikes.
• American Craftsmanship & Assurance: Proudly engineered, manufactured, and assembled in Portland, Oregon USA – backed by our legendary King Lifetime Warranty for peace of mind on every epic backcountry journey.

Elevate your ride reliability and responsiveness – invest in hubs built to endure the toughest trails and amplify your connection to the dirt.
