Mondraker Dune RR
Mondraker Dune RR
The Full Scoop on Mondraker Dune RR
The 2026 Mondraker Dune RR is the pinnacle of the Dune lineup — a no-compromise superenduro eMTB built for riders who demand the absolute best suspension, drivetrain, and stopping power available.
The RR steps up to Fox Podium 29 GRIPX2 Factory Kashima suspension with a DHX2 coil shock, delivering the most controlled, predictable feel on the gnarliest terrain. SRAM X0 Eagle AXS T-Type wireless shifting eliminates cables and delivers instant, precise gear changes under full load. SRAM Maven Bronze 4-piston brakes with HS2 200mm rotors provide massive, fade-free stopping power.
Sharing the same Stealth Air Full Carbon frame, Zero Suspension System, and Forward Geometry as the Dune R, the RR pairs the Bosch Performance Line SX Gen4 Smart System motor with a compact 400Wh Powertube battery for 600W peak power at just 45.2 lbs. The ONOFF S6 carbon handlebar and Onoff Pija internal dropper round out a build spec that punches at the highest level of the category.
