This is the Summum as the Mondraker Factory Racing team rides it. The RR shares the 6061 alloy Stealth Evo chassis and 200mm of Zero Suspension travel with the rest of the range, but everything bolted to it is a level up - and the Team Edition paint makes no secret of where it came from.
The suspension is the headline. A RockShox Vivid Coil Ultimate shock replaces the Select+, giving you a far wider tuning window, and the Boxxer Ultimate fork adds a Charger 3.2 RC2 damper with independent high and low-speed compression. On a downhill bike that's the difference between coping with a track and actually setting the bike up for it. Spring rates are still matched to frame size, so you're not starting from scratch.
Braking moves to SRAM Maven Ultimate with SwingLink levers, lever pivot bearings and HS2 rotors (220mm front, 200mm rear) running sintered pads. The drivetrain is SRAM's wireless XX DH AXS - seven speeds, an Eagle AXS Pod controller and a tight 10-24T XS 797 cassette, driven by an XX DH T-Type crankset. Wheels step up to DT Swiss EX 1700 Classic rims on 350 hubs, with the 72T Ratchet DEG system in the rear for near-instant engagement.
The frame itself is unchanged from the R, which is the point: mixed 29"/27.5" wheels, a 12x157mm rear axle, UDH, ISCG 05 tabs, and the same geometry kit in the box with +/- 5mm headset cups, a lower shock mount flip chip and +5mm / -5mm dropouts. Sizes run M, L and XL.
