Shimano Dura-Ace RT900 Ice Tech Freeza Disc Rotor – Silver
The RT900 Dura-ace features Shimano ice tech technology where the rotor surface is made of a clad steel, alloy and steel rotor construction, which allows heat generated from braking to transfer quickly through the aluminium core. Achieving surface temperature drops of around 50c. This also helps achieve long pad life, less noise and less fade. This is a durable lightweight and rigid rotor, using the proven Shimano Centre-Lock system giving increased strength and security with an easy set-up. Precision cut and drilled braking surface improves pad clearing in muddy conditions while aiding cooling under high load.
