Natura BIKES
Stagione 2021

With 20 years of innovation by Mondraker’s engineers, designers and World Cup-winning riders, the 2021 Summum features the all-new Stealth Alloy frameset – with Forward Geometry

Summum Alloy has our latest race-proven Zero Suspension, featuring 200mm travel and new metric kinematics that make rocks and hazards disappear, and help you soak up the big drops like you’re floating. It works with the proven piggyback/coil Fox Van RC Performance shock, and is paired with the RockShox BoXXer Select RC 29 DebonAir fork up-front – with 200mm of Charge RC-damped travel to keep you on track. Add in the new fast, rock-ready 2.4in Michelin DH34 tires and super-responsive SRAM Code R 4-pots on 203mm rotors, and the new Summum Alloy is ready to race as hard as you are!
