Mondraker Dusty RR Bike

The Mondraker Dusty RR sits at the top of Mondraker's e-gravel range, built for riders who want electric assistance without the bulk that usually comes with it. This is a gravel bike first and an e-bike second — the kind of machine designed to disappear underneath you on long mixed-terrain days, not announce itself with a whirring motor and a heavy downtube. The Dusty Stealth Air Carbon frame and matching carbon fork keep the silhouette close to a standard gravel bike, and a 12x142mm rear axle and integrated dropout speed sensor round out a frame built specifically around its electric drivetrain rather than adapted from one.

Power comes from a TQ HPR motor system paired with a 580Wh HPR battery and a color HPR display. TQ's systems are known in the e-road and e-gravel world for their compact size and low drag when the motor isn't actively assisting — a meaningful detail on a bike you'll also want to pedal hard on unassisted climbs or fast descents. It's an approach built around subtlety: enough support to extend range and take the edge off long days in the saddle, without turning the ride into something that feels motorized.

The drivetrain is where the Dusty RR gets interesting. Mondraker pairs SRAM Force AXS E1 shifters and hydraulic disc brakes with a SRAM X0 Eagle AXS T-Type rear derailleur — a mullet setup that borrows mountain bike gearing for a gravel cockpit. A single 42t X-Sync Eagle chainring runs against a 10-52t XS-1295 cassette, giving you a genuinely wide range for climbing loaded or tired, without the front shifting complexity of a 2x setup. It's the kind of drivetrain choice that makes sense on a bike meant for varied terrain rather than a single discipline.

Zipp 303 XPLR S wheels wrapped in 700x50 Goodyear XPLR Inter tires give the Dusty RR real capability off the paved surface, and the frame's 50mm max tire clearance leaves room to run wide if the terrain calls for it. The Onoff S9 GR carbon handlebar adds 16 degrees of flare for extra control when the road gets loose, and it's finished with Fizik's tacky Terra Solocush tape for grip when things get rough. Mondraker builds the Dusty RR around its Forward Geometry philosophy — long front-center, shorter stem — which the brand applies across its lineup to keep handling stable and predictable at speed, a trait that matters as much on a gravel descent as it does on a mountain bike.

This is a bike for riders who want to cover more ground, faster, without sacrificing the feel of a proper gravel bike underneath them. Long backroad routes, mixed-surface adventure rides, and gravel days that used to end early because your legs gave out before the terrain did — the Dusty RR is built for exactly that kind of riding, with a spec sheet that reflects Mondraker's position at the premium end of the e-gravel category.
