Technology

Freeza Disc
Shimano Ice-Tech technologies have enabled the creation of a highly advanced rotor equipped with aluminum fins for better heat control. Thanks to a larger surface area dedicated to heat dissipation, the disc ensures significant temperature reductions. This, in turn, results in a 20% increase in performance durability and a 20% longer pad lifespan.

Fixing ring included.
