Zero Suspension System
ZERO is Mondraker’s proprietary most efficient, best performing and super capable suspension system. ZERO is individually designed, set up and optimised for the best pedalling efficiency and biggest hit capability on each Mondraker full suspension model across the range, from little Factor 24 or F-Play 24 models to Summum Alloy and Summum Carbon World Cup & World Championship winning downhill bikes.
ZERO is a virtual pivot suspension system with an exclusive dual link design. The most unique and exclusive feature of ZERO is that the shock floats between the two suspension links and is compressed from both ends. This makes the rear suspension extremely supple on small bumps and big hit capable, really the most acknowledgeable and astounding feature of every Mondraker full suspension bike.
ZERO superior technologies’ main advantages are Zero power loss -a completely stable ride when pedalling-, Zero pedal kickback-minimum chain growth throughout the suspension travel-, Zero brake jack –isolated braking and suspension forces- and what we call Zero bumps, its great ability to soak up any type of bump keeping the rear wheel efficiently planted on the ground.
STEALTH ALLOY
STEALTH ALLOY encompasses all processes in the creation of the frame, from the industrial design to the specific production of each of its tubes with the calculation of the most precise details. Each tube and part is carefully designed to carry out a specific function while striving to achieve the lowest possible weight. Stealth technology is evolving every year with optimised shapes and internal updates to deliver the best riding experience in our aluminium frames.
You can find STEALTH ALLOY technology in Summum, SuperFoxy, Foxy, Factor 24 & 26, Leader, F-Play, Play, Chaser, Dusk, Crafty and Level series models.
