Improved version of the aluminum 6061 alloy is a perfect compromise between high stiffness and low mass. It is very resistant to external conditions, breakages and impacts. Thanks to the butting of all the frame tubes, we were able to retain toughness of the construction, while at the same time, reduce construction mass.
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.
Method used to shape tubes by pressurized liquid injection. This technology primarily creates a lighter structure characterized by higher durability and precise finishing.
Painting by placing electrified powder paint molecules onto aluminum, which requires heat treatment. After sintering the varnish surface creates a perfectly smooth coat which is very resistant to mechanical damage.
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.
Precise technique to even out the welding which raises the aesthetic qualities of the structure without having a negative effect on durability.
