Your wheels are arguably the most important component on your mountain bike, which is why we’ve developed an all-new aluminum line of Reserve trail, enduro and e-bike wheels. Reserve aluminum wheels have been designed and developed to provide a product that rivals the performance of our much-loved carbon wheels, but at a much more accessible price point. And with our industry-leading lifetime guarantee, you can feel confident you will be enjoying these wheels for years to come. FEATURES: Fillmore Valves Standard: Our patented Fillmore valve represents a game-changing leap forward in technology, with a high-flow design that eases tubeless set up and eliminates the traditional, delicate, clog-inciting valve core of yesteryear. Tested and Approved: With over a year of ride and lab testing, the 30|HD AL wheels are designed to withstand any abuse you can throw at them. Like all Reserve wheels, they are supported by a lifetime guarantee. Asymmetrical Design: Asymmetrical rims, like those on the 30|HD AL, build stiffer, stronger and more reliable wheels by improving the bracing angles and equalizing the spoke tensions between the drive and non-drive side spokes.
