Shimano 105 SM-RT70 Center 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.

SM-RT70 Ice Tech rotors give excellent performance using the proven Shimano Center Lock system providing excellent rigidity and security with an easy set-up.

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 Ice Technology disc brake rotors and pads reduce heat buildup and provide consistent and reliable braking power available. The rotors feature a 3-layer stainless steel-aluminum-stainless steel sandwich design that radiates heat for better performance. The brake pads have an aluminum radiating fin that helps dissipate heat throughout the system. Together, Ice Technology rotors and brake pads deliver a quieter ride while reducing brake fade and extending pad life for a more reliable and confident riding experience.

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.

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

• 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
