Summum is Mondraker’s flagship bike, that boasts a world championship-winning design for ultimate downhill rides! Summum 27.5 uses HHG Internal Cable Routing for a minimalistic, clean design.
Mondraker’s unique zero suspension system helps with stability and control by absorbing the strongest vibrations and keeping your wheels planted on the ground even on the bumpiest of the trails. This superior suspension design offers zero power loss for pedaling stability, zero pedal kickback for minimum chain growth throughout travel, zero brake jack for isolated braking & suspension forces, and zero bumps for absorbing even the slightest bumps for extreme rear wheel stability.
Downhill riders will love the safety and confidence offered by Mondraker’s proprietary forward geometry design. Forward geometry also helps with improved handling, overall control, uphill precision, and stability in tough terrains.
The durable stealth alloy frame helps with resistance and mobility for better speed and performance. Stealth Alloy technology uses smartly designed tubes catering to specific functions with the goal of achieving the lowest weight.
Summum 2021 sports high-performance front and rear derailleurs and 27.5” tubeless-ready tires, for ultimate precision and grip through uneven and rough trails. Extreme riders can conquer rigorous trails in the comfort of consistent and unstoppable braking power from durable, all-terrain compatible, MTB brakes. Summum is loaded with additional features like dual raw enduro bearings, super-boost rear axle, and hydroformed tubing for traction and control.
