Description

Description

The Shimano RT-CL900 brake discs are part of the Shimano Dura Ace R9200 groupset. These Shimano RT-CL900 brake discs have been further optimised to improve heat dissipation. Shimano introduced a different composite that significantly reduces heat and reduces brake disc deformation. The new material provides even more braking power and control. On top of that, the spider has an open design to handle the wind better.

- Shimano RT-CL900 brake disc including internal lock ring

Assembly

How to assemble the disc brake ?
For brake discs, you have 2 different ways of mounting depending on the washer. One has an internal fit that you can tighten with a cassette removal tool without a pin. If the inside of the key is open, it can reach far enough over the axle of the wheel. The other version is an external fit that you can tighten with a bottom bracket key.

Reliably good

- Frank 8 January 2024

I chose the Shimano brake discs because they are reliably good, have a low weight and also look good in my eyes. The design of the RT-CL900 is just a bit more dynamic than the previous generation RT-MT900. I haven't ridden the bike yet, but assume this is just fine for this brake disc too and no different from previous generations.
