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.

• Ideal 180mm Diameter: The 180mm size provides a great balance of stopping power and weight, offering strong leverage without the added mass or clearance issues of larger rotors.

• Durable Two-Piece Construction: Features a rigid stainless steel braking track mounted to an aluminium alloy spider. This construction ensures excellent stiffness and improved heat dissipation over standard one-piece rotors.

• Reliable Heat Management: The design and aluminium spider effectively manage and dissipate thermal energy to maintain consistent stopping power and reduce the potential for fade during demanding use.

• Enhanced Service Life and Quiet Operation: The structural stability of the two-piece design aids in thermal regulation, which helps to extend pad life and minimize unwelcome braking noise.

• Secure 6-Bolt Mounting: Utilizes the universally accepted 6-bolt mounting interface, providing a strong, secure, and straightforward installation onto any compatible hub.

• 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.

• Consistent Braking Finish: The braking track is finished for a smooth, high-contact surface, ensuring an excellent and predictable braking feel with strong initial bite.

• Simplified Sizing: This rotor is specifically offered here in the 180mm size, utilizing the reliable 6-bolt attachment system.
