We count on the Reserve 30|SL Mountain Wheel with DT Swiss 350 90T hub when weight, reliability, and responsiveness are non-negotiable. Built for modern trail riding, this wheel brings XC-like efficiency with the toughness to handle daily mileage on burly singletrack. The Reserve carbon rim delivers a perfect balance of stiffness and compliance, while the DT Swiss 350 hub with upgraded 90T ratchet system ensures every pedal stroke counts-especially when we're dancing through tight switchbacks or punching up technical climbs. The 30mm internal width supports the wider tires we prefer for traction and control, while asymmetrical drilling improves spoke tension balance for long-term durability. Add in the Reserve lifetime warranty and this is a wheelset we can ride hard and trust for seasons to come. Whether lacing it into a lightweight downcountry build or refreshing a do-it-all trail bike, the 30|SL with DT Swiss 350 is our go-to for reliable speed and snappy engagement.
