Summum is still Mondraker’s flagship and a leading bike on the DH international circuit. This year its two models are premiering aesthetic changes that make them even more attractive and have been fitted with some top-end components to achieve a record weight for a bike of this kind. The price of the new Summum bikes will ensure they remain the one most seen in DH races.
Zero is the name of Mondraker’s proprietary suspension system and is used on all of its full suspension bikes. In 2012 the system is being extended to the Cross Country Racing category with 100 mm travel and new optimization for XC racing. That means you can enjoy all the advantages of Zero from XC to Downhill covering all the mountain bike categories in between.
The Zero System belongs to the category called “Virtual Pivot” suspension systems. The most significant difference of the Zero system in relation to the other alternatives within this category is that the rear shock is floating between two links and is compressed from both ends. Depending on the optimization of the system and based on its usage, the lower plate compresses the rear shock an average of about 35% of its total length and the upper plate approximately 65%. The positioning of the rear shock together with the compression that the shock receives from both sides makes this system unique.
There are four key points that make the Zero Suspension system so incredibly effective:
Zero power loss. The system prevents any unwanted movements produced whilst pedalling resulting in maximum efficiency without extra compression or extension of the rear suspension.
Zero pedal kickback. Chain length growth throughout the suspension travel is insignificant avoiding any backward movement of the crank set that could lead to poor pedalling efficiency or cadence.
Zero brake jack. Rear brake forces do not alter the suspension system. The rear shock will absorb impacts without changing its function whilst using the rear brake.
Zero bumps. The main characteristic of the system is its excellent absorption capacity at the same time as it provides high pedalling efficiency. The optimized trajectory of the rear axle and the linear nature of the rear shock assure very effective impact absorption.
The Stealth Technology is the most advanced industrial design and structure optimization technology used in the Mondraker range. Stealth encompasses all processes in the creation of the frame, from the inspiration and creation of the industrial design to the calculation of the most precise details that optimize each part for a specific function.
Stealth offers and innovative design, characterized by flat faces and sharp edges as opposed to the traditional curved or rounded shapes. Each tube and part is carefully designed to carry out a specific function striving to achieve the lowest possible weight of every specific part of the frame. Due to the optimization of the production process, selecting the best materials, using butted tubing technology and applying an alloy of different aluminums, Mondraker´s ultra light Stealth frames are extremely resistant with great stiffness, especially in the high stress areas of the frames where it suffers most.
The Summum Pro Team downhill bike at 15.6 kg is the Stealth technology flagship. It´s a DH World Cup winning bike with outstanding stiffness and strength and a record braking ultra-light weight.
Stealth technology is used in the Factor, Foxy, Dune, Zenith, Durham and Summum series.
The purpose of this kit is to adapt the geometry to your preferences according to your riding style or the type of circuit you use. This way you can make adjustments from an extreme geometry that riders would use during the world cup DH, to a geometry more adequate for Freeride. The kit contains 3 headset reducers made of CNC for 0º, +/- 1 - +/-2 and 4 different drop-outs to adjust the length of the chainstay into 435mm, 440mm, 445mm or 450mm together with adjustable brake adaptors in accordance to the different lengths of the chainstay.
