RLT 9 4-Star GRX Gravel Bike

When that yellow sign tries to warn of the pavement’s end, we know that’s where the adventure truly begins with the crunch of gravel beneath our tires. Whether we’ll be out just until sunset or for multiple days, the freedom of riding beyond the reach of skinny tires brings joy like none other. The Niner RLT GRX is purpose-built for those meanders along mountain streams and canyon walls, to propel you further than you’ve been before, with the gearing to hold up speed to make town line sprints. With massive tire clearance for rubber and the unfortunate mud spot, and comfortable geometry, the RLT offers all-road capability that’s confident, powerful, and capable.

Shimano’s gravel-specific GRX group provides precise shifting across undulating terrain, with a clutch-mechanism rear derailleur and ergonomic hoods and levers for greater comfort. A 47 / 32t crankset gives us a wide range for both the cruiser flats and the stout off-road climbs we’ll encounter as our route takes us over the pass to a new valley. Schwalbe G-One 40mm tires paired with Stan’s Grail wheels provide a capable wheelset for the RLT, ready for a variety of terrain and able to roll through and over any kind of sand or grit that comes your way.
