    RLT 9 STEEL

    All-day comfort, confidence, and control

    Steel is truly real

    It’s not about where you’re at, it’s about where you’re headed. 

    The RLT 9 Steel is for the purist, the rider who’s after the classic aesthetics of smooth, supple steel. Whether it’s on pavement or gravel road, this bike craves long adventures. With plenty of room for all your gear, the only thing stopping you from your next ride is your imagination. Go ahead, take the ride of your dreams with the RLT 9 Steel.

    RLT 9 Steel bike frame

    Reynolds 853 steel

    Our love affair with air-hardened Reynolds 853 steel started early. From early flirting with the ROS 9, to the first SIR 9, to our current RLT 9 steel, we’ve crushed on ferrous frames for over 15 years.

    Why does Niner steel still feel so real?

    In practical terms, Reynolds 853 is a nearly perfect material for creating bike frames. Rather than being weakened by heat, the frame tube junctions actually strengthen after TIG welding. This allows the use of thinner, lighter frame tubes without any sacrifice in durability or strength.

    Additionally, steel-framed bicycles have a well-earned reputation for rugged, dependable reliability. Steel has a way of brushing off the inevitable scratches, dings, and rough treatment that accompanies the best adventures. No matter if you have a cross-continent excursion or a county line commute, the RLT 9 steel loves to be loaded up and rolled out.

    Steel frame, RDO carbon fork

    The RLT 9 Steel features our all-new RDO carbon fiber fork. The combination of steel frame and carbon fork is sure to offer a supple ride, regardless of duration. This beautifully designed fork is composed of famous Race Day Optimized carbon fiber, which is built with a unique process that optimizes complete compaction of the carbon layers under heat and pressure. By maximizing the carbon-to-resin ratio in the finished product, we keep this fork light and stiff while improving compliance over rough surfaces.

    We paid mind to aesthetics and functionality in this fork. The brake hose is routed internally through a fully sleeved guide tube. Multiple rack, fender, and cargo mounts make light work of heavy loads, so go ahead, add another day of bikepacking on to your trip. The 12x100mm thru-axle and flat mount disc brake attachments are compatible with contemporary components. If you find yourself wanting to push the limits on a long haul self-supported ride, we’ve got you covered. The new fork features internal wire routing and fitment for a hub dynamo powered light, so the only thing keeping you from riding into the night is your bedtime.

    Tire size compatibility for any adventure

    Get ready to swoon. With more tire clearance than ever before, the RLT 9 Steel can accommodate tires as wide as 700x50c. Does your next ride require more rubber on the road? Not to worry, swapping out wheels is easy. This bike can accommodate 650b wheels and fit tires as wide as 2.0. Go wild with wheel and tire combinations, just keep it rubber side down out there.

    Frame features fit for going farther

    Are you a steel connoisseur, an adventure addict, weekend bikepacker, gear hoarder, over packer, grocery-getter or commuter extraordinaire? If you answered yes to any of these, the RLT 9 Steel was made for you. This dream build has 26 mounting points that give you the option to outfit your bike with as many bags, bottles, and racks as you need. You can haul anything from a love letter to your hockey team’s uniforms...

    Moving on- We’ve also designed custom bags for each frame size that mount directly to the frame. No more straps or buckles flying around. Just a cleanly designed frame ready for the next journey.

    Cleanliness is next to godliness. Our internal cable routing keeps the frame looking tidy. Want an even sleeker bike? Single-speed calling your name? With our PF30 bottom bracket shell, it’s easy to fit a geared or single-speed drivetrain. More gears your thing? This bike is compatible with either mechanical or electronic shifting. Plan on getting rowdy on your ride? Throw a dropper post on, for safety.
