Aerodynamics and feel. The design of the 3D Levers starts from a process of analysis and testing in the wind tunnel. It has been found that, in sporty use at high speeds, the force of the air pressure has a significant effect on the braking system. To reduce this effect, a drain has been carried out at the outer end of the lever that reduces the existing pressure to a minimum to guarantee optimal operation. Machined from a block of aluminum and anodized, these levers offer wide adjustment possibilities by moving on sliding bearings with return springs, thus guaranteeing precision and reliability. In addition, the joint allows the levers to retract in the event of a fall, reducing the possibility of breakage. Finally, the surface treatment guarantees a better grip, also completed with the colored silicone rings, which in addition to being an added customization detail, allow a better grip when adjusting the lever.
