The floating brake disc offers high performances thanks to heat-treated material.
It offers the best result in combination with Newfren brake pads.
The peculiarity of the floating brake disc is the rotor (made of steel) which is unlinked from the central hub (it freely moves on ergal 7075 mounting buttons machined from solid, anodized and heat treated).
This system highly reduces the stress of the disc therefore the wear.
Moreover, it offers a better disposal of the heat, thanks to the easy brake rotor adjustment.
The optimized cooling, given by this system, avoids brake pads moving back inside the caliper, during long descents.

The hub is made by steel.
