Why We Like The RLT 9 RDO 4-Star GRX 800 2x Gravel Bike

Take the Road Less Traveled on the RLT 9 RDO 4-Star GRX 800 2x Gravel Bike — a rare mix between a performance road bike and a dedicated gravel grinder. It's rugged, robust, and delivers everything we want for purposeful riding through unruly terrain. With Race Day Optimized carbon fiber, the RLT 9 sails through miles on end with lightness, speed, and agility. It's what we want to take with us anywhere, every time. Extra tire clearance, multiple fitments for accessories and cargo, and slick frame features mean we can tackle everything from bikepacking to canyon climbs and turbulent training. The RLT 9 gives us the room we need to roam and the necessary geometry to keep us comfortable the whole way.


The RLT 9 is a multi-tool of a bike that can tackle everything from dusty trails to loose gravel and tarmac. Light and stiff carbon fiber satisfy even the most competitive gravel racers. Its bump-absorbing compliance makes for a forgiving ride that leaves us free to floor it no matter how choppy the surface. The RLT 9 also features an all-new RDO carbon fiber fork, further increasing compliance and stiffness for a smooth ride. Fireroad geometry, with a longer chainstay, lower bottom bracket height, and a slacker headtube angle, keeps us comfortable no matter how many miles we're putting away. Rack, fender, and cargo mounts make heavy loads laughably easy to take along with us, and there's even internal wire routing and fitment for a hub dynamo-powered light. This way, we can ride well past sunset if we so choose. As far as tire clearance goes, the RLT 9 can fit rubber as wide as 700 x 50c for a beefier option. If we plan on getting super rowdy, the RLT 9 makes room for a dropper post. Last, the PF30 bottom bracket shell makes it easy to fit a geared or single-speed drivetrain.


*Due to unprecedented demand in the global supply chain and the bike industry over the last 18 months, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be minor. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.
