Mondraker Summum R Downhill Mountain Bike 2027 in Quasar Blue / Black

Season:2027

Brand:Mondraker

Code:27SUMMUM RBlue Black

Developed through years of World Cup downhill racing experience, the Mondraker Summum R brings competition-proven technology to riders seeking exceptional performance on demanding terrain. Its redesigned 6061 Stealth Alloy Evo frame features hydroformed tubing, optimised stiffness and Mondraker's Forward Geometry, delivering precise handling and stability at speed. The updated Zero Suspension System provides 200mm of rear wheel travel, with improved mid-stroke support and sensitivity to maintain traction and control through rough sections, steep descents and technical features. A mixed-wheel configuration combines a 29-inch front wheel with a 27.5-inch rear wheel, balancing rollover capability with agility.

The Summum R features a RockShox BoXXer Select RC 29 fork with 200mm of travel and a DebonAir+ air spring, paired with a RockShox Vivid Coil Select+ rear shock for consistent suspension performance under demanding conditions. Its downhill-specific SRAM GX DH 7-speed drivetrain delivers precise shifting and closely spaced gearing suited to competitive riding, while SRAM Maven Base four-piston hydraulic disc brakes provide powerful stopping performance. Large 220mm front and 200mm rear rotors help maintain braking control during prolonged descents, giving riders the confidence to carry speed into challenging terrain.

Designed for riders who demand a personalised setup, the Summum R offers up to 27 geometry configurations through adjustable headset cups, a lower shock-mount flip chip and interchangeable rear dropouts. These adjustments allow riders to fine-tune reach, bottom bracket height and chainstay length to suit different courses and riding preferences. DT Swiss F 1900 Classic wheels, Maxxis downhill-specific tyres and a durable Onoff cockpit complete a build designed to withstand demanding riding conditions. Integrated cable routing, sealed suspension bearings and protective frame guards further enhance durability, making the Summum R a capable choice for downhill racing and bike park riding.
