Shimano Steps RT-EM810 Centre Lock Disc Rotor

Shimano RT-EM810 E-Bike disc brake rotors for speed sensor systems deliver powerful and consistent brake performance in all riding conditions. The Ice Technologies Freeza rotor significantly reduces heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches. Shimano's Centre Lock mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.

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).

Reduce more 10°C by high heat dissipation paint (equipped: SM-RT900 and RT-MT900).

Features

• RT-EM810 Ice Tech E-bike rotors with built in speed sensor magnet providing consistent braking performance through energy control
• 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
• Rotor houses the magnet necessary for speed sensor function on Shimano Steps equipped E-bikes allowing frame clearance for wider tyres
• Compatible with E8000 / E6000 systems and for rear wheel use only
• Rotors are durable lightweight and rigid, using the proven Shimano Centre 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
