The RLT 9 RDO is Niner's carbon gravel race frame, built here with SRAM's Apex XPLR 12-speed group and a rigid carbon fork. The frame is the draw: internal cable routing, thru-axles, rack and fender mounts, and clearance for either 700 x 50c or 650b x 2.0" tires make it a race bike that doubles as a commuter or light tourer. Apex XPLR gives a wide 1x range with a 40T chainring and 11-44T cassette, so steep loose climbs are covered, though the jumps between gears are bigger than a 2x setup. It suits riders who want one fast carbon bike for gravel, mixed-surface commuting and bikepacking rather than a dedicated racer or a steel tourer.
It checks today's price at every store, compares the alternatives and answers in about a minute.
Owners rate the RLT 9 RDO highly, with most giving it full marks. They single out the frame's ride quality, the mount options and the tire clearance. The common gripes are the 1x gearing gaps and the parts spec being modest for a carbon frame.
