The RLT 9 Steel Frameset 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 frameset craves long adventures. With plenty of room for all your gear, spec it out to your personal preferences and hit the roads with the RLT 9 Steel. 

The Reynolds 853 steel frame 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. 

The RDO carbon fork is sure to offer a supple ride, regardless of duration. The brake hose is routed internally through a fully sleeved guide tube. Multiple rack, fender, and cargo mounts make light work of heavy loads. The 12x100mm thru-axle and flat mount disc brake attachments are compatible with contemporary components. The 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.
