The Reserve 30 HD Alloy 29in i9 1/1 Super Boost Wheelset is a do-it-all 29in wheelset built to withstand the abuse we can't avoid from rough off-road trails while keeping us riding faster, further, and longer. The asymmetrical rim design provides the stiffness and reliability we look for in a wheelset, while the shallow profile takes the discomfort out of harsh impacts to improve the overall ride quality.
