Technology

Disco Freeza
Ice-Tech' Shimano technologies have enabled the creation of a highly advanced rotor equipped with aluminum fins for greater heat control. Thanks to a larger surface area dedicated to heat dispersion, the disc guarantees significant temperature reductions. This, in turn, generates a 20% increase in performance life and a 20% extension of pad life.

Fixing ring nut included.
