Niner RLT Steel


While other frame materials fall in and out of favor, steel stands the test of time. Finely constructed steel frames, crafted and welded by the best builders, have continued to be the benchmark other materials measure themselves against. The RLT9 Steel delivers a flawless synthesis of form and function into a frame that makes every ride open for adventure. From mounting panniers and racks for camping to traveling the gravel road that curves out of sight, the RLT9 is more than capable for the open road.

You ride the road less traveled. Adventure calls for a well-engineered frame with technology capable of keeping you moving. The Niner RLT9 is where performance, durability, and ride quality meet. Every consideration was made with convenience and compatibility in mind. We’ve blended the historic Reynolds 853 tubing with modern design characteristics utilizing thru-axle technology and a tapered steel headtube. To conquer any and all terrain, the RLT9 can accommodate either a double or triple chainring. If simplicity is your thing, a single ring is an option.
