Shimano RT-CL700 Ice Tech Rotor - 160mm External Lockring

Shimano's RT-CL700 Ice Tech Rotor delivers consistent braking performance through advanced heat control, long pad life, and a reliable Centre Lock fit. Its layered steel and alloy construction disperses heat efficiently, while the refined rotor surface improves pad contact and cooling.

Key Features and Benefits:

• Clad steel-aluminium-steel rotor construction: The rotor's layered build pulls heat away from the braking surface into the aluminium core.
• This helps lower surface temperatures by around 50°C, reducing thermal stress and supporting consistent braking under load.
• Ice Tech heat management system: When used with Ice Tech pads, rotor temperatures drop from about 400°C to 300°C.
• This results in less fade, better brake control, and improved performance on long descents or under repeated braking.
• Refined rotor surface: The contact surface clears debris and improves airflow around the pads.
• This helps maintain braking efficiency, lowers pad wear, and ensures quieter operation in wet and dry conditions.
• Shimano Centre Lock mounting with included lockring: The system uses a spline mount and lockring to secure the rotor.
• This setup offers strong rigidity and a fast, secure installation process for both internal and external lockring options.
• Which lockring do I need Choose the lockring that matches your hub and axle setup.
• Internal-spline lockrings suit quick-release and most 12mm thru-axle hubs, while external-spline lockrings offer extra axle clearance and are required for most 15mm and 20mm thru-axle hubs.
• If replacing an existing rotor, matching the lockring type already fitted is usually the simplest option.
• See Images for visual example of each.
• The RT-CL700 is designed to maintain braking stability in high-heat situations where fade can limit control.
• Its construction and pad interface work together to prolong pad life, reduce noise, and ensure reliable performance under pressure.
• This makes it a practical choice for riders who demand lasting braking consistency across variable terrain and conditions.
• Upgrade your braking system with a rotor built for controlled heat dissipation, quiet performance, and long-term pad efficiency—all with simple and secure setup.
