The 2015 Niner RLT 9 Steel is the steel adventure road bike that will offer performance, durability, and the awesome ride quality of steel.
The RLT 9 Steel frame gets a tapered headtube, Press Fit BB30, low profile inset rear brake mount and a 12×142 Maxle rear thru axle. The fork’s dropouts are QR, and there is all external brake and shift cable routing. The Di2 wiring runs internally and heads to the seatpost battery.
Top and down tubes are triple butted Reynolds 853DZB (double zone butted). The rest of the tubes are standard chromoly steel, which allows Niner to get more creative with the shaping to “Gravel Tune” the frame. In particular, that’s done with the shaping and size of the seat stays to take advantage of steel’s properties. The seat tube is externally butted and is capped off with a butt-friendly 27.2 seatpost. All frame sizes have two water bottle mounts inside the front triangle and one on the bottom of the downtube. A full complement of rack and fender mounts let you take the bike on multi-day adventures.
