Shimano SLX SM-RT70 Centre Lock Disc Rotor

SM-RT70 disc brake rotors deliver powerful and consistent brake performance for all riding conditions. The Ice Technologies 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

Shimano Ice Technologies components deliver more consistent braking performance by reducing heat buildup in the system. This helps prevent brake fade, which can happen when a rider applies the brakes repeatedly and strongly over a short period of time, such as when descending a long, steep hill.

Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.

Clad rotors as well as Clad Brake pads significantly reduce heat build-up in the brake system. This in turn reduces fading, which ensures consistent high performance even on long downhill stretches, It also results in a longer pad life and substantially quieter braking.

Centre Lock

The Centre Lock 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.

Features

• SM-RT70 Ice Tech rotors give excellent performance using the proven Shimano Centre-Lock system providing excellent rigidity and security with an easy set-up
• 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 contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life
• Comes complete with lockring
