KROSS LEVEL B+ is the highest model in our 29'' collection. A wider seat tube and bottom bracket made in Pressfit system allow increased rigidity of the bracket's shell. This means more energy being passed onto the drive. The rear triangle was shortened which allows an improved agility. A newly implemented element, the 12x142mm size rear axle, significantly increased bicycle's rigidity. LEVEL B+ is equipped with Rock Shox Sid XX shock absorber as well as SRAM XX highest group components. The DT Swiss XRC 1250 Spline wheels are equipped with Schwalbe Rocket Ron tires.

Our top models for mountain biking are made from carbon sl. Its unique characteristic is the arrangement of carbon fibers in a strictly defined manner, so that the whole construction is exceptionally rigid against horizontal forces, while at the same time, being absorbent to vibrations. Such a solution allows a maximum transmission of the driving force to the rear wheel, while at the same time, retaining the necessary suppressing properties.
Direct mounting of the front gear increases rigidity and therefore, the precision of operation. Reliability and easy assembly make this solution an absolute necessity for a professional bike.
Inner cable routing improves the longevity of cables and shells, protecting them from mud, sand and rain. it helps save precious grams and achieves the flawless, sports-professional character of the bicycle
The post mount system is a crucial solution for a racing bicycle. Braking precision is increased due to the elimination of unnecessary adapters, which influences the stiffness of the connection between the frame and the clamp. Better heat rejection prolongs the life of brakes and improves their efficiency.
Widened seat tube helps to achieve increased bottom bracket stiffness – even 8% more even the solution introduced last year. The fibre arrangement and a square profile make the construction less sensitive to the hundreds of watts put into riding during a race.
Wheel hub in the 142 x 12 mm standard means wheel rigidity comparable with downhill specific bikes but with easy dismounting system. Wider hub allows to stiff the whole construction of wheel and rear triangle which adds precision and stability during riding.
