Product Description

Shimano Dura Ace RT-CL900 Ice Tech FREEZA Rotor With Internal Lockring 

Dura-Ace grade RT-CL900 Ice Tech rotors providing consistent braking performance through energy control, using revolutionary stainless steel / alloy 3-layer sandwich construction that manages heat while riding

The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg C.

When used with Ice Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round

FREEZA rotors allow the alloy core to extend out from the braking surface as a fin to providing added cooling

Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion

Rotors are durable lightweight and rigid, using the proven Shimano Center Lock system giving increased strength and security with an easy set-up

Precision cut braking surface improves pad clearing in muddy conditions while aiding cooling under high load

Large alloy spider is a highly rigid and lightweight support for the rotor surface

Super polished braking surface gives excellent braking performance

Sizes: 140mm or 160mm 

CENTER LOCK

3D Aluminum carrier​

Optimized 3D-shaped aluminum carrier is designed purposefully in every single dimension and achieves lightweight and superb heat distortion resistance.
This prevents the entire rotor from deforming due to heat and reduces rubbing noise while riding.

ICE TECHNOLOGIES FREEZA​

ICE TECHNOLOGIES FREEZA provides consistent braking performance with less brake fade, less noise and longer pad life.
