RLT 9 Steel Frameset

While an ultra-stiff and uber-lightweight carbon frameset might be prized in competitive road and cross arenas, when your exploring the outdoors, doing some loaded touring and racing nothing but the sun, durability and ride comfort is king. Sure, carbon or some other exotic material has its place when marginal gains separate the sport's best from a spot on the podium, but let's remember that the original racing frame material was steel and it's still the one that's trusted when venturing off the beaten path and miles of uncertain chunky gravel define your travel. If this sounds like where your riding intentions lie, have a look at the RLT 9 Steel Frameset from Niner and build up your dream bikepacking or all-road rig.

When we look back at what we wrote above, it sounds like this bike can't be competitive, but that's simply not the case and it'll happily toe the line at a gravel race or fondo, however, that Road Less Traveled ethos means that the RLT Steel is most at home on remote, wilderness trails and spending week-long trips exploring the unknown. The frame's geometry is a fairly good mashup between Niner's hardtail mountain frames and that of its barrier hopping, mud bogging 'cross-specific BSB frameset. Making it more adept off the racecourse, the RLT 9 features longer chainstays, a lower bottom bracket, and a slacker head tube angle. This provides a lower center of gravity and a position more "in" than "on" the bike for more confident cornering and improved stability, both of which you can never have too much of while bombing down rut strewn, washboard riddled descents at speed. The longer wheelbase also affords improved tire clearance that lets you run rubber up to 1.75-inches, that's just over 44mm for our metric friends. This helps the bike float over braking bumps while remaining agile for quick line choices on mellow singletrack. This RLT is so versatile in fact, you might even find yourself navigating the urban jungle on it as your daily commuter bike too.

In this day and age where almost every frame, and component for that matter, is constructed from carbon, Niner bucks the trend and is one of few brands this side of a custom builder that still constructs frames from Reynolds 853 steel. The material is prized for its super compliant ride over bumpy surfaces, yet it doesn't sacrifice much in the way of stiffness, so it still accelerates swiftly. The ride is a revelation if you've never ridden steel before, and Niner does choose a carbon fork to drop some weight without detracting from that magical steel ride. The Carbon RDO fork helps soak up the hits while smoothing out road vibrations but don't get confused thinking it's a lightweight, spindly road fork, far from it, as it has disc flat mounts, an MTB approved 15mm thru-axle anchoring the hub in the dropouts, and rack mounts with a 45-pound carrying capacity that's happy to share the load during overnight duties and commutes. Niner has constructed rigid carbon trail forks for years so we're not in the least worried about durability here.

Other frameset features include its PF30 bottom bracket shell, allowing you to choose between a geared or masochistic single-speed adventure. Internal shifter routing is mechanical and Di2 ready and the frame accommodates 1, 2, or 3x drivetrains.

I have tried to select a build for this bike, but your website does not allow me to add a package or individual components to the base frame. Thank you.

I've been looking at this frame for a while. Something I am wondering though is that it says it has Internal cable routing but everything I see has the provisions for external cable routing. Is the shifting internal and the braking external? Or something else. Thank you

Hi Mathew, I have the prior model year frame for the RTL. Your understanding is correct - External for the brake lines (Except internal for the front fork - new for this model year) . Drive train is also external except if your running electronic rig (ie Di2). The frame has ports for the wiring. It rides great on paved roads & on fire roads. The cables are external for ease of servicing when it’s used for bike camping ⛺️. I am working my way in that direction. Here’s a pix of last year’s model. Enjoy the journey!
