Mondraker SUMMUM RR - 2021


100% Satisfaction Guaranteed

The Summum RR features the pure pro’s choice, the new Fox DHX2 Factory shock, on the R it’s the new Fox DHX2 Performance Elite, and there’s no messing with the Fox Van RC Performance on the Summum (all 70mm stroke). On each model the rear suspension has the same 200mm rear wheel travel – just as the pro’s race with. But the kinematics are expertly adjusted to get the best from the shock, geometry and frame material as a package: “The leverage ratio of the new 2021 Summum is more supple off the top, more progressive and it has a greater rising rate than its predecessor,” explains Israel Romero.


  • Updated geometry and refined suspension kinematics
  • More progressive leverage ratio, generating a greater rising rate action
  • Mondraker M068 derailleur hanger

    RIDING TYPE:  Downhill, Freeride/Bike Park
    WHEEL SIZE:  29"

    The 2021 Summum might look and sound radical – but remember, this is an evolution. You still get the underlying handling characteristics of Forward Geometry and Zero Suspension.

    The changes you see for the new model are part of Mondraker’s ongoing programme of development, learning year on year, race after race and week-in, week-out about the best materials, geometry, technologies and components, it’s precision crafted – to make your fastest ever downhill rig… the 2021 Summum!

    Mondraker also kept the base Summum model – and the RR frameset – in a 27.5 option for the riders who prefer it. The RR frameset also comes in a ‘best of both worlds’ dedicated MX-style mullet option: 29 front and 27.5 rear.

    “Some riders would probably like to experience the mullet frameset combo as this option has proved to be very popular at World Cup racing for the last couple of seasons.” - Israel Romero.



      And there’s new suspension and kinematics.
      Oh yes! Soaking up the biggest hits – and smoothing out the small stuff with amazing sensitivity – at the front of the new Summum, you’ll find the New Fox 40 29 FIT Grip2 Performance fork on the R and RR with 203mm of Kashima-coated travel and the moto-inspired Grip damper keeping you on track. The super dependable RockShox BoXXer Select RC 29 DebonAir fork is up-front, with 200mm of Charge RC-damped travel leading the way on the Summum.
      And keeping you planted at the back end, you still get the very best from the World Cup-proven Mondraker Zero Suspension system – specially updated for the new wheelsizes, with enhanced kinematics and a set of new shock options.

      So, it’s longer!
      All the Summums are longer this year. New frame, new wheelsize, new geometry… the reach is longer, and the bikes are even better balanced than before. The 2020 Summum 29er has four size options, with reach measurements of 430mm (size S), 450mm (M), 475mm (L), and 500mm for the XL. The Summum 27.5 is available only in Small and Medium size options, with the exact same reach measurements – with the fundamental geometry characteristics maintained across all the combinations.

      The new Stealth Alloy uses the same aluminum raw material that graced the 2020 model but the frameset is now significantly more refined, with slimmer tubes and updated geometry layout. With a nod to the Foxy and SuperFoxy Enduro and Super Enduro profiles, it looks slimmer and faster than before – because it is slimmer and faster!

      As well as the design and the material, what really sets the 2021 Summum apart is the expertise and craftsmanship in creating each frameset. You can feel Mondraker's love for DH in every tube, in every weld and in every finish. And that love shines through in their precision crafting.
