What is Ice-Tech Technology?

Shimano Ice-Tech brake pads quickly dissipate heat generated during braking thanks to their aluminum cooling fins . This allows:

• Braking power does not decrease.

• Fade (performance loss due to overheating) is reduced.

• A more stable braking feel is achieved during long descents.

• Brake disc and pad life is extended.
