Mondraker SUMMUM RR Mullet Full Suspension Downhill Mountain Bike 2027 in Black/Blue/Alloy

Season:2027

Brand:Mondraker

Code:SUMMUM RR Mullet Black/Bl

The Mondraker Summum RR Mullet is a premium downhill race bike engineered for riders who demand maximum speed, adjustability, and World Cup-level performance on the toughest tracks. Developed alongside Mondraker’s Factory DH team and refined through elite-level racing, it combines advanced Zero Suspension kinematics with downhill-specific geometry to deliver exceptional control, traction, and stability at race pace.

Its Stealth Evo alloy frame features 200mm of rear travel paired with a 200mm RockShox Boxxer Ultimate fork for outstanding suspension sensitivity and high-speed composure across rough and technical terrain. The mullet wheel setup combines the rollover confidence of a 29-inch front wheel with the agility and responsiveness of a 27.5-inch rear wheel for aggressive downhill riding.

The updated Zero Suspension System improves mid-stroke support and responsiveness, while an extensive geometry adjustment system allows riders to tailor the bike to different tracks and riding styles. Premium SRAM Maven Ultimate brakes, wireless SRAM XX DH AXS drivetrain components, and DT Swiss wheelset technology complete a race-ready downhill bike built for uncompromising performance.

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.

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.
