What Our Gearhead® Experts Are Saying: "The MX setup with the 30 HD feels like the perfect combo—nimble in the back, stable up front, and tough enough to shrug off everything from rock strikes to bike park abuse. The new OneUp hubs are buttery smooth and engage fast when I need them most."The Reserve 30 HD Aluminum MX Wheelset blends 29-inch front wheel stability with 27. 5-inch rear agility, delivering a ride that’s confident through the chunder and responsive through tight, technical corners. Reserve engineered these rims with aggressive riders in mind—featuring a 30mm internal width that fits modern tires perfectly, and an asymmetric profile for added stiffness, durability, and balanced spoke tension. At the center of it all is OneUp’s first-ever hub, built to handle the hardest hits and the most demanding climbs. The Boost 6-Bolt hub is machined from lightweight 7075-T6 aluminum and rolls on premium Enduro ABEC-5 bearings. Inside, dual 44-tooth ratchets provide fast 8-degree engagement for quick, efficient power transfer. Combined with Reserve’s patented Fillmore valves for hassle-free tubeless setup and full E-bike approval, this wheelset is dialed for years of high-performance riding. Topped off with an exclusive silver finish, it's a standout upgrade for any mixed-wheel rig.
