Shimano RT-CL800 Centerlock Rotor 180mm Ice-Tech Freeza (with Integrated Magnet): The Smart Partner for Cool Performance

🧲 OVERVIEW: A MASTERPIECE OF THERMAL MANAGEMENT INTEGRATED WITH E-BIKE TECHNOLOGY

The Shimano RT-CL800 Centerlock 180mm Ice-Tech Freeza rotor combines superior heat dissipation technology with a function critical for modern e-bike systems: Integrated magnetic locking ring. This special "MJ" (Magnet) variant is available only. Consistent braking power and quiet operation during long descents. not only to offer, but also To provide speed signals to Shimano STEPS E-Bike systems. It creates a direct integration point. Its 180mm diameter offers ideal balance for aggressive Trail, Enduro and performance E-Bikes.

⚙️ DUAL-TECH ENGINEERING: FREEZA + E-BIKE INTEGRATION

1. Ice-Tech Freeza Heat Management System

• Sandwich Construction: Rotor, stainless steel - aluminum - stainless steel It has a three-layered structure. The aluminum core transfers heat away from the steel surfaces. 3 times faster It transmits and distributes.

• FREEZA Cooling Fins: Optimized aluminum structures in the rotor arm increase the surface area. It further reduces the system temperature.

• Temperature Drop of Up to 100°C: This technology reduces the rotor surface temperature during braking compared to conventional rotors. It can reduce the temperature by approximately 100°C.

• Results: Minimal brake fade, consistent modulation, high braking power, reduced noise, and extended brake pad life.

2. Lockring with Integrated Magnet

• Function: This circle, Shimano STEPS EW-SS302 speed sensor It is the signal source for.

• How does it work? A magnet embedded in the ring sends a magnetic signal to a nearby speed sensor every time the wheel rotates. The sensor transmits this signal to the E-Bike control unit. It measures the speed and adjusts the pedal assist accordingly.

• Importance: Your e-bike It must correctly enforce the speed limit (e.g., 25 km/h), provide speedometer data, and disconnect support at the right time. It is a vital component. Integrating the magnet into the rotor, Clean, risk-free, and professionally installed. provides.

• Internal Tool Holder: Ring, internal 6-point Allen wrench It is tightened with a tool. This means a cleaner look and no need for a traditional Shimano spline tool.

📏 TECHNICAL DETAILS AND PERFORMANCE

• Diameter: 180mm. Trail and Enduro bikes Standard for the front brake, powerful for the rear brake. It is an option. It offers an excellent balance of power, heat, and weight.

• Thickness: 1.75mm. Shimano's standard rotor thickness. Optimized for durability and heat dissipation.

• Installation: Centerlock (CL). Used with Shimano CL hubs. It is incompatible with 6-bolt (ISO) systems.

• Friction Surface Width: 14mm. The large surface area improves heat dissipation and brake pad contact.

• Recommended Brake Pads: Resin or Sintered. Ice-Tech rotors with resin brake pads. maximum silence and performance Metallic brake pads are suitable for more aggressive use, but they can increase rotor wear.

• Weight: ~147g (measured). Despite its superior thermal performance, it is extremely lightweight.

🛠️ USAGE AND COMPATIBILITY

• Main Use: Shimano STEPS E6000/E7000/E8000 series E-Bikes. The rotor provides the necessary speed data for the e-bike's electronic system to function properly.

• For use on standard bicycles: Yes, it's available. The magnet serves no function in a standard bicycle, but it fully utilizes the rotor's braking performance. Only visually is a magnet housing visible on the ring.

• Speed ​​Sensor: NOT INCLUDED IN THE PACKAGE. Rotor, only EW-SS302 It is the signal source for the sensor. The sensor must be purchased separately.

• Compatible Brake Assemblies: Compatible with all Shimano hydraulic disc brakes (Deore, SLX, XT, XTR, GRX, 105, Ultegra, Dura-Ace) and other brands of Centerlock calipers.

⚠️ CRITICAL INSTALLATION AND MAINTENANCE NOTES

1. Torque Value: Centerlock ring, as specified by the manufacturer. torque value (usually 40 Nm) It must be tightened. Overtightening can damage the hub or ring; leaving it loose is a safety risk.

2. Magnet Location: The ring can generally be attached in any direction. However, if your e-bike has a speed sensor, the sensor must be attached to the magnet. 1-3 mm distance And make sure it is positioned so that it is correctly aligned.

3. Brake Pad and Rotor Cleaning: New rotor and brake pads before installation. It should be cleaned with isopropyl alcohol to remove grease and fingerprints.

4. Bed-in Procedure: The new rotor/pad set should be used before reaching full braking performance. It should be acclimatized with 20-30 moderate braking applications.

✅ WHO IS IT IDEAL FOR?

• Shimano STEPS E-Bike Owners: For speed sensor integration mandatory or strongly recommended It is an upgrade.

• Performance E-Bike (Other Brands) Users: Those seeking superior thermal performance (the magnet will become ineffective).

• Trail and Enduro Riders: For those who want good heat management and reliability, with a 180mm front rotor.

• Those Suffering from Brake Noise and Fading: Ice-Tech Freeza technology offers a direct solution to these problems.

Evaluation:
Shimano RT-CL800 180mm Ice-Tech Freeza (MJ), It brings together the best of both worlds: Professional-level brake cooling performance and seamless integration for e-bike electronics. Choosing this rotor will not only improve your brakes, but also your E-Bike. It also guarantees the accurate and reliable operation of the intelligent system. Your investment, your safety, performance and the technological integrity of your bike This is a comprehensive investment. Especially for STEPS users, this is not a standard rotor, It is an integral and intelligent part of the system.
