Shimano Steps RT-MT800 Centre Lock Disc Rotor

RT-MT800 Ice Tech E-bike rotors with built in-speed sensor magnet providing consistent braking performance through energy control.

Technology

Ice Technologies Freeza

Ice Technologies combined with Freeza disc brake rotor construction rapidly dissipates heat for more consistent braking performance in extreme conditions, longer pad life, and less brake fade and noise.

Benefits and features:

• Lightweight clad rotors with heat dissipating paint on exposed aluminium layer segments provide superior cooling, consistent brake performance, and lighter operation under all conditions
• Clad brake pads with Aluminium/Stainless fins support rapid heat dissipation which helps reduce maintenance, provide longer pad life, and create less brake fade and noise

Ice Technologies and Freeza provide consistent braking performance with longer pad life, less brake fade and noise.

The lightweight and highly efficient three-layer sandwich structure of stainless steel–aluminium–stainless steel enhances heat dissipation.

140°C reduction in heat (vs stainless steel disc brake rotor).

CentreLock

The CentreLock system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.

• Light weight
• Center Lock compatible hub has only spline mount and a lock ring. This means the lightweight of hub and rotor compared to 6-bolt mount system
• Lock ring rotor mounting system
• Allows easier and faster rotor installation. Easy maintenance
• Secure fixing by spline mount
• Improves braking efficiency

Features

• Uses revolutionary stainless steel / alloy 3-layer sandwich construction that manages heat while riding
• The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 degrees C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 degrees C, this provides great improvements in performance all round
• Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion
• With internal lockring housing the magnet necessary for-Speed sensor function on Shimano Steps equipped E-bikes allowing frame clearance for Wider tyres
• Rotors are durable lightweight and rigid, using the proven Shimano Center Lock system giving increased strength and security with an easy set-up
• Precision cut and drilled braking surface improves pad clearing in muddy conditions while aiding cooling under high load
• Large alloy spider is a highly rigid and lightweight support for the rotor surface
• Super polished braking surface gives excellent braking performance
