Downhill racing is where it all started for Mondraker, and the Summum is the product of many years at the very top of the sport. It has been tuned, tested and thoroughly hammered by some of the world's fastest riders on the gnarliest race tracks going.
The alloy Summum frame shares its geometry with the premium carbon version and is covered by the same limited lifetime warranty. It delivers 200mm of travel through the updated Zero Suspension System, a virtual pivot design where the shock floats between two links and is compressed from both ends, making the rear end supple over small bumps yet hugely capable on big hits. This MX version runs a 29" front and 27.5" rear wheel, and a geometry kit with headset cups, a shock mount flip chip and adjustable dropouts is included.
The RR MX has the best build of the alloy Summum range: Fox Factory Kashima suspension with a 203mm Fox 40 GRIP X2 and DHX2 coil shock, SRAM Maven Ultimate brakes with a 220mm front rotor, e*thirteen Grappler carbon wheels and a SRAM X01 DH 7-speed drivetrain with carbon cranks.
