Niner RLT 9 Steel Frameset

Niner RLT 9 Steel Frameset

Steel Adventure Seeker

Some things are just timeless. Like red brick is to buildings, steel is to bicycles. You may have noticed that finely constructed steel frames, crafted and welded by the best builders continue to be highly sought after for their unblemished combination of form and function. So it only made sense for Niner to reimagine their aluminum RLT 9 with supple, trustworthy Reynolds 853 Steel, breeding the perfect adventuring rig. The RLT 9 Steel is a no-brainer for mounting up som racks and bags, rounding up the gang and pedaling out for a weekend of building campfires, pitching tents, and traveling the road less traveled.

Like the original aluminum RLT 9, the RLT 9 Steel was intentionally built for the curious and spontaneous. It starts with revered, lightweight 853 tubing which excels at absorbing and smoothening out ground chatter, while maintaining a knife-edge stiffness and responsiveness. If you mainly stick to the pavement or fire roads you can use a 28-32c road tire, or if you want something a little wider (up to 1.75”) you can swap out to a mountain-spec 29” wheelset thanks to the 142mm rear hub spacing. Geometry-wise, it's built for all-day riding with slightly longer chainstays, slightly lower bottom bracket, and slacker head tube angle make this a real gravel grinder for the long haul.

To make this a bike you can truly ride on and off road all day, the RLT 9 Steel features a gravel-tuned, custom painted Niner Carbon fork to eat up all those road and “not-road” vibrations. Connecting the dots between classic frame design and modern technology, the RLT 9 Steel is augmented with thru-axle technology and a tapered steel headtube, greatly improving the overall ride quality and handling.

The RLT 9 Steel features internal dropper post routing and uses a PF30 bottom bracket shell allowing you to run it geared or single speed with Niner’s BioCentric 30. Some of the clever, less-noticeable frame features include rear rack pannier braze-ons for when the adventure lasts longer than a few hours, and three water bottle mounts ensuring you have fuel in places that don't.

The RLT 9 Steel is exactly what you’d think of when hearing that Niner made a 700c, steel drop bar bike: beautiful, versatile and ready to seek out the unknown.

  • Supple, Trustworthy Reynolds 853 Steel frame

great bike
very comfortable ride and handles well for a gravel do all bike ,touch on the portly side but light components and wheels should get it down to 20ish pounds ,don't care for the cable routing on the downtube from a cosmetic point , i wish a 55cm would have been a choice .

Most versatile bike on the market. Smooth riding, light
I needed a bike to do tours where long days and uncertain conditions prevail. I love the ride quality and quick acceleration of this bike. Flexible tire sizes let me take fire roads when paved roads are unsafe. I think you can get to just about anywhere on this bike

Well engineered, great value
Thanks to Niner for offering a reynolds 853 steel frame in a type of bike that seems to only be offered in Aluminum and Carbon these days. They thought of everything here, provsions for racks, fenders, DI2, geared or singlespeed, full length cable housings, cage mounts on the fork, 140mm brakes, everything you'd expect on a modern all purpose bike.
Also pleasantly surprised to find all the small parts to build this frame properly. Cable housing clamps, zip ties, headset, seatpost clamp, axle end for geared or singlespeed, stem spacers, top cap anchor, you name it.
The only negative I have found is the rear thru axle QR system protrudes about 30mm from the frame. Waaaay out there. I will be replacing it with a thin flange hex head thru axle.

Miner RLT Steel
purchased to replace a Ridley XC bike. Rough on gravel, no provisions for rack mounts.

O Ly two rides in on the Niner. But enough that I know it was a good choice, far more comfortable and what I was looking for.
Two rides in. All smiles.

Great frameset
Excellent frameset...built it up with an Ultegra groupset and TRP Hy/Rd brakes. It rides super smooth and has become my go-to bike for long rides on gravel or pavement. My other bikes are carbon, and I can say that this is the most comfortable of all of them.

PROS: Attractive Design, Durable, Easy To Install

BEST USES: Casual Riding, Road Biking

Better than I expected
Delivery was a little whacky but only due to the size and color I wanted being back ordered. Jenson was cool and very helpful with updates. The frame arrived in perfect shape with no damage or problems.
