RR Mullet 2026
The Mondraker Summum RR Mullet is a purpose-built downhill and bike park weapon in a mixed-wheel (mullet) configuration. Built on a 6061 alloy Stealth Evo hydroformed chassis with 200mm of travel front and rear, the Summum RR delivers maximum confidence on the most demanding tracks.
SRAM's fully wireless XX DH Transmission AXS 7-speed drivetrain eliminates mechanical cables from the equation, while Maven Ultimate 4-piston brakes with sintered pads and 220mm front rotors provide the stopping power you need at speed. A comprehensive Geometry Kit with reach-adjust headset cups, flip-chip lower shock mount, and modular dropouts makes the Summum RR one of the most adjustable DH platforms available.
