Shimano RT-CL800 Ice Tech FREEZA Rotor with Internal Magnet Lockring - 180mm

180mm Shimano RT-CL800 Ice Tech FREEZA Disc Brake rotor with internal magnet lockring

The Shimano RT-CL800 rotor is available in a 180mm size, maintaining the high performance of the Ultegra/XT component level. It features ICE TECHNOLOGIES FREEZA, incorporating a three-layer stainless steel/aluminum construction and radiator fins to significantly reduce heat buildup by up to 50'C. While the original 'LJ' suffix applies to the 203mm version with an internal magnet lockring, the 180mm Centre Lock rotor offers the same superior heat management. This design guarantees consistent, powerful, and quiet braking, effectively minimizing fade and extending the service life of your brake pads.

Features:

• 180mm Ultegra/XT Performance: This specific rotor diameter is set at 180mm, offering the superb stopping power and heat management characteristic of the XT/Ultegra component level.

• Consistent Braking Control: The revolutionary stainless steel/alloy/steel three-layer sandwich construction actively controls thermal energy, ensuring highly consistent and powerful braking performance.

• Advanced Heat Dissipation: The aluminium core allows heat generated during braking to quickly radiate away, achieving surface temperature reductions of approximately 50'C.

• FREEZA Cooling Technology: The alloy core extends outward as a fin structure, providing added cooling surface area to further dissipate heat and prevent brake fade.

• Benefits of Thermal Management: Due to this improved heat dispersion, riders experience longer pad life, reduced noise, and minimized fade, especially under heavy load.

• Rigid Center Lock Mounting: Utilizes the robust Shimano Center Lock system, ensuring a durable, lightweight, and rigid mounting interface for quick and secure setup.

• Precision Braking Surface: The finely cut braking surface not only aids in cooling but also improves mud clearance, maintaining reliable performance in challenging, wet conditions.

• Lightweight Aluminium Support: A large aluminium spider acts as a highly rigid and lightweight platform, securely supporting the external rotor ring.

• Lockring Versatility: The 180mm size is available with various lockring options (internal, external, or internal with integrated magnet) to fit diverse applications.
