The Mondraker Summum R Mullet is a race-focused downhill bike engineered for maximum speed, control, and adjustability on the toughest tracks in the world. Developed alongside Mondraker’s Factory DH race team and refined on World Cup circuits, it combines proven Zero Suspension kinematics with modern downhill geometry to deliver exceptional composure, traction, and confidence at race pace.

Its Stealth Evo alloy frame features 200mm of rear travel paired with a 203mm Fox 40 GRIP Performance fork, delivering outstanding suspension sensitivity and mid-stroke support for aggressive downhill riding. The mixed-wheel mullet setup combines the rollover speed of a 29-inch front wheel with the agility and responsiveness of a 27.5-inch rear wheel for fast, technical terrain.

The updated Zero Suspension System improves handling and responsiveness while extensive geometry adjustment options allow riders to fine-tune the bike for different tracks and riding styles. Powerful SRAM Maven brakes, downhill-specific SRAM GX DH drivetrain components, and robust e*thirteen wheels complete a highly capable race-ready downhill machine built for maximum performance.

Warranty Information for Mondraker:

Mondraker offers an extended lifetime warranty for all its frames against defects in materials or manufacturing. Exclusions and terms apply.
It should be emphasised that each bicycle/frame has a life-cycle which will vary depending on the type of material and its construction. This life-cycle may be shortened by the form and type of use, or lack of appropriate maintenance and care. The lifetime warranty will therefore be entirely dependent on the optimal life-cycle determined by Mondraker for each specific Product.

All warranty claims for Mondraker components or original parts will be handled through an authorised Mondraker distribution point, and the original commercial invoice must be provided.

Mondraker points of sale will handle the warranty of third-party manufacturers' components, with each manufacturer being responsible for the warranty of its components used in the product.
