Shimano SMMT900 Centerlock brake disc

The RT MT900 brake discs are classified by Shimano as part of the XTR and Saint series, but can of course also be used with other Shimano disc brakes.

The Shimano RTMT900 Ice Tech Freeza brake discs feature additional cooling fins. The Centrelock brake discs on the aluminium carrier are manufactured using a sandwich construction. The aluminium core is encased by the steel braking surface. This significantly reduces heat build-up and increases the durability of all Shimano brakes.

Shimano RTMT900 Ice Tech brake disc technical specifications:;

• Disc diameter 180 mm
• Weight: Disc approx. 140 grams
• Centre-lock mounting

External locking ring:

This lockring, featuring external splines for the tool, can be fitted to all hub types, from 20 mm thru-axles to quick-release assemblies

External Spline Lockring – external tool engagement: 44 mm outer diameter, 16-tooth spline. A Hollowtech II tool such as the Shimano TL-FC36, TL-FC32 or TL-FC33 is required to fit the Center-Lock lockring.

Shimano Ice Tech Freeza:

Freeza brake discs exhibit even less fading due to lower heat build-up compared to standard Shimano IceTec brake discs. The three-layer sandwich construction consists of stainless steel flanges and an aluminium core with integrated cooling fins. The two-piece design with the aluminium carrier dissipates heat effectively. The dirt-repellent design extends the service life of both the disc and the pads.

This Ice Tech brake disc is compatible with all Shimano hydraulic disc brakes.
