Mondraker has introduced its new Summum DH bike, available only in aluminium construction and mullet (mixed wheel size) configuration. All models will have reach adjustment via interchangeable headset cups, angle adjustment using a flip chip on the shock mount and adjustable chainstay length.
The top-spec build will include SRAM’s new wireless electronic seven-speed DH groupset, XX DH AXS Transmission, also released today.
The Mondraker Summum has a strong lineage, with the first prototype including Mondraker's Zero Suspension System appearing in 2009 when Fabien Barel rode a prototype Summum to win the Maribor DH World Cup.
Zero Suspension System
The Summum still uses Mondraker's proprietary virtual-pivot style suspension system, seen on all of Mondraker’s full-suspension bikes. The Zero Suspension System connects front and rear triangles with two short, co-rotating links.
Although team riders were seen using a Summum with an idler wheel in 2024, the new Summum retains a more traditional low-pivot suspension setup delivering 200mm of rear-wheel travel.
The shock’s angle is more horizontal, showing that the way it’s actuated has been refined compared to the previous-generation bike.
The suspension is adjustable via a flip chip in the shock mount. Mondraker says the adjustment is primarily for geometry changes, but that it also changes leverage ratio at the beginning of the travel and increases progression by 1.5 per cent. Mondraker suggests this can be used to adapt the bike to different rider preferences, terrain and shocks.
Geometry
There are three sizes on offer: medium, large and extra large, with 450mm, 480mm and 510mm reach respectively.
Mondraker has built a range of adjustment into the Summum for different riders’ bodies and riding styles.
Swapping the removable headset cups on the Summum changes the reach by +/- 5mm.
The flip chip alters the bottom bracket height by +/- 5mm and the head tube and seat tube angles by +/- 0.35 degrees.
Removable dropout inserts on the Summum can shorten or lengthen the chainstay by +/- 5mm to fine tune how the bike rides.
These adjustments add up to 27 possible geometry configurations. All Summums (including the frame-only option) include the dropout kit and reach adjustment headset cups as standard, so no extra purchase is needed to access the full range of geometry customisation.
Lineage
The Summum is the only bike ever to score a clean sweep at a downhill World Championship, with a 1, 2, 3 for Danny Hart, Laurie Greenland and Flo Payet at Val Di Sole in 2016.
In 2017, Markus Stöckl took a standard Mondraker Summum to 167.6Km/h down a Chilean mountain, making it the fastest production mountain bike in the world.
This latest version of the Summum has been refined by the Mondraker DH team, including two-time Hardline and World Cup winner Rónán Dunne.
During the 2025 season, the prototype had bolt-on stiffening plates in the rear triangle. These enabled the stiffness to be tuned for optimum traction and Mondraker to decide on the balance of stiffness and compliance in the final production frame.
2026 Mondraker Summum build options
There are two bike builds and a frame-only option to choose from:
The Summum RR is the top-spec bike with a RockShox Boxxer Ultimate 29in fork, RockShox Vivid Coil Ultimate shock, DT Swiss EX1700 Classic wheels, SRAM Maven Ultimate brakes and the new electronic SRAM XX DH AXS T-Type seven-speed drivetrain.
The Summum R is the more budget-conscious of the two builds, featuring a Fox 40 Performance fork and Fox DHX2 Performance shock, e*thirteen Grappler Flux wheels, SRAM Maven Base brakes and SRAM GX DH seven-speed drivetrain. The Summum R is available in a Fog Grey / Superblack / Solar Flare colourway.
