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.
