Description
The Shimano SM-RT66 is a highly durable and performance-oriented brake rotor, positioned within the robust SLX/ZEE component level for demanding mountain bike use. This specific rotor measures 180mm in diameter, striking an excellent balance between powerful stopping force and weight saving, making it ideal for trail and all-mountain riding. It employs the secure and traditional 6-bolt mounting system for compatibility with a wide range of hubs. The rotor's solid two-piece construction ensures reliable heat management and excellent modulation, providing consistent braking bite and control in all terrain.
Features:
-
Robust Performance Level: Classified at the SLX/ZEE level, this rotor is purpose-built for high durability and reliable performance, handling the stresses of aggressive trail and all-mountain riding.

Optimized Braking Track: The precisely machined braking surface is engineered to efficiently clear mud and debris while promoting airflow for effective cooling and dependable performance.
-
Lightweight, Rigid Support: The aluminium alloy spider acts as a highly rigid and lightweight foundation, offering steadfast support for the external stainless steel braking surface.
