Mondraker Summum R Mullet Downhill Bike – Fog Grey
Available now at The Rolling Fix, Liverpool
Take on the toughest downhill tracks with absolute confidence aboard the Mondraker Summum R Mullet in striking Fog Grey. Designed for riders who demand precision, speed, and control at the highest level, this elite downhill machine blends cutting-edge engineering with race-proven performance.
At the heart of the Summum R is Mondraker’s Stealth Evo 6061 Alloy frame, built around the brand’s advanced Forward Geometry and updated Zero Suspension System. Delivering a massive 200mm of rear travel, this bike is engineered to soak up the harshest impacts while maintaining incredible stability at speed. The mullet setup—29” front wheel paired with a 27.5” rear—gives you the perfect balance of rollover capability and agile handling.
Suspension duties are handled by a premium Fox Performance Elite setup, featuring the Fox DHX2 rear shock and Fox 40 Float GRIP fork with 203mm travel. Together, they offer exceptional tunability and responsiveness, ensuring you stay composed on technical descents, big hits, and high-speed sections.
The Summum R is built to perform under pressure, with powerful SRAM Maven Base 4-piston brakes delivering consistent stopping power via oversized 220mm front and 200mm rear rotors. A robust SRAM GX DH 7-speed drivetrain ensures smooth, reliable shifting, while the Truvativ Descendant DH crankset provides maximum durability for aggressive riding.
Rolling on e*thirteen Grappler Flux wheels paired with a Maxxis Assegai front tyre and Minion DHR II rear tyre, this bike offers outstanding grip, traction, and control in all conditions. Whether you’re racing downhill or pushing your limits in the bike park, this setup is built to handle it all.
Comfort and control are further enhanced with Onoff cockpit components, including a wide 800mm handlebar and adjustable stem, plus an Ergon SM10 DH saddle designed for downhill performance.
