Shimano Ultegra RT-CL800 Center Lock Rotor

The Shimano RT-CL800 Ice Tech Center Lock Rotor delivers top-tier braking performance, combining XT/Ultegra-level precision with advanced heat management technology for consistent, fade-free stopping power.

This rotor’s innovative 3-layer stainless steel–aluminium–stainless steel sandwich design rapidly dissipates heat, dropping surface temperatures by up to 50°C — and when paired with Ice Tech pads, temperatures can fall from ~400°C to ~300°C, dramatically boosting performance and control.

• Cooling fins extend the alloy core beyond the braking surface for even greater heat dispersion
  
• Ice Tech construction ensures long pad life, reduced noise, and minimal brake fade under sustained braking
  
• Durable, lightweight, and rigid design using Shimano’s proven Center Lock system for secure, easy installation
  
• Precision-cut braking surface enhances mud clearance and cooling under load
  
• Large alloy spider provides lightweight, rigid rotor support
  
• Super polished braking surface ensures an excellent, smooth braking feel
  
• Supplied OE with lockring
  
• Diameter: 140mm
  
• Mount type: Center lock
