What our customers are saying about Shimano RT-CL900 Lock Externo brake disc

Experience top-tier Shimano quality with this Dura-Ace brake rotor. It delivers spectacular, powerful braking performance with no vibration, even during sudden stops. A clear upgrade from Ultegra, this disc is quieter and offers excellent grip in the rain. Its lightweight, stylish, and aerodynamic design provides a cool look and is reliable for long-distance rides on mountainous terrain

One of the most reliable rotor out in the market. Would really recommend to use for long distance. It's really worth and the grip is good even during raining days.

Dura-ace never disappoints

I love the new Dura-Ace discs, the vibration during sudden braking disappears completely and in areas with crosswinds they affect much less than my old Ultegras!
