The RLT 9 maximizes your freedom and access to the Road Less Traveled. Nothing is stopping you from achieving your off-road aspirations with affordable, high performing materials, elegant engineering, and a fully-featured frameset. No surface can’t be ridden, no side roads that must be skipped. And best of all, the RLT 9 offers unbeatable value at every level.
Niner’s 6061 aluminum RLT 9 is welded with hydroformed aluminum tubing. This material is universally praised for its affordability and versatility. Before welding, Niner is careful to shape the tubing to optimize strength, durability, and stiffness while keeping it as lightweight as possible.
The latest version of their vaunted aluminum gravel frame features a new, forged chainstay yoke to improve tire clearance and stiffness. This design leaves them with an elegant and simple multi-talented platform.
Upfront, the RLT 9 features their all-new RDO carbon fiber fork. It’s made from Niner's famous Race Day Optimized carbon fiber built with a unique process that optimizes the carbon layers' complete compaction under heat and pressure. They keep this fork light and stiff while improving compliance over rough surfaces by maximizing the finished product's carbon-to-resin ratio.
The brake hose is routed internally through a fully sleeved guide tube, which means no more fishing for wires. Multiple racks, fenders, and cargo mounts make light work of heavy loads. The 12x100mm thru-axle and flat mount disc brake attachments are compatible with contemporary components. Finally, the new fork features internal wire routing and fitment for a hub dynamo-powered light for fully off-grid adventures.
With more tire clearance than ever before, the RLT 9 can accommodate tires as wide as 700x50c. And if you prefer smaller diameter wheels with wider rubber, interchangeability is easy. Swap to 650b wheels and fit tires as wide as 2.0.
Everyone has a different reason for the ride. Durable, affordable aluminum is ideal for a range of rides. Anything is possible - from ripping around campus to a cross-continent cruise, the RLT 9 has it handled.
The RLT 9 is made for gravel roads around the world. And if you’re serious about literally riding anywhere in the world, this bike will get you there.
Multiple mounting points on the frame give you the option to fit bottles, bags, racks, fenders, and, frankly, almost any accessory that could be bolted to your bike. Custom bags mounted to the frame won’t require straps, and gear of all sorts can ride along with you.
Internal cable routing keeps the frame looking tidy. Combined with a PF30 bottom bracket shell, it’s easy to fit a geared or single-speed drivetrain and either mechanical or electronic shifting. And if your rides tend to take a turn for the rowdy, there’s even room to fit a dropper post.
