Niner RLT 9 Bike

RLT 9 Aluminum

Ride Beyond the City Limits

The unmatched versatility of the RLT 9 aluminum gravel bike gives you the freedom to explore virtually anywhere. Transition seamlessly from asphalt to cinder path, swerve onto singletrack, cut across gravel, and roll back into the city — all without skipping a beat or breaking the bank.

Adventure Awaits... All Aboard Aluminum

Built from hydroformed 6061 aluminum, the RLT 9 is engineered for strength, durability, and efficiency. Carefully shaped tubing maximizes performance while keeping weight low. A new forged chainstay yoke improves tire clearance and stiffness, creating a refined platform ready for adventure.

Fork in the Road? No Problem

The RLT 9 features Niner’s RDO carbon fork, constructed with Race Day Optimized carbon fiber for a perfect blend of stiffness and compliance. Internal brake hose routing and numerous mounts for racks, fenders, and cargo ensure the fork performs as beautifully as it looks — even under load or in rugged terrain.

Choose Your Wheels, Choose Your Adventure

With clearance for 700x50c or 650b x 2.0" tires, the RLT 9 adapts easily to any terrain. Whether you're cruising country lanes or tackling rocky trails, this bike is built to deliver comfort and control wherever you roam.

Frame Features Fit for Going Farther

The RLT 9 aluminum frame is packed with adventure-ready features — including 26 mounting points for bottles, bags, racks, and accessories. Internal cable routing keeps everything tidy, while the PF30 bottom bracket shell allows for a geared or singlespeed setup, with compatibility for both mechanical and electronic shifting. Dropper post ready, too.
