D84 Carbon SL is a light weight racing compound. D stands for double carbon material consisting of T800S and M40J materials combined with nanoalloy resin. The frame is exceptionally rigid against horizontal forces,while at the same time, being absorbent to vibrations. Extremely light weight and race tough construction for the most demanding racers.
Conical frame-head with gradually changing diameter from 1 1/8” at the top to 1.5” at the bottom increases durability as well as stiffness of the construction and results with greater precision of steering.
Bearings are contained inside cups and the cups are pressed into the frame to increase peddling efficiency, decrease wear of the bearings and create a better transfer of the driving force to the wheel.
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.
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.
We created a system of exchangeable dropouts in order to protect our frames
as much as possible. In case of damage they can be easily and quickly exchanged. Screws or
a special nut are used for the dropout in order to minimize frame damage.
Guarantee large brake force and good modulation of it even in the most severe weather conditions, they also last for much longer than traditional brakes.
