Shimano Ultegra BR-R8070 Flat Mount Disc Brake Caliper

With a low-profile Flat Mount design, the Shimano Ultegra R8000 series hydraulic disc brakes provide greater control
in all conditions without interrupting the aero lines of road bikes.

Technology

Ice Technologies

The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a
negative impact on the braking performance. 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, aluminum 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.

Ice Technologies piston in order to achieve optimized lightweight, high rigidity and heat
dissipation. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used
to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss.

One Way Bleeding

“One Way Bleeding” was developed for quick and easy prevention of air in our hydraulic system. We have streamlined
the oil route throughout the system to prevent air bubbles from being captured in the system.

One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

Features

• Ultegra hydraulic road disc brake offer an ideal balance of light weight and efficient braking, making it
  the perfect choice for both enthusiast and competitive riders
• Front wheel use for flat mount forks with adapter to flip between 140 and 160mm
• Oversized 22mm ceramic pistons optimized for heat insulation, lightweight and stiffness
• Opposed 2-piston design reduces leading effect and optimal pad wear increases braking control
• Increased pad to rotor clearance reduces the chance of rotor drag
• Direct flat mount and open design allows easy and quick wheel replacement
• Forged caliper design is lightweight and rigid
• One way internal fluid circuit makes bleeding easy
• Mineral oil brake fluid is non-corrosive and less hazardous than conventional hydraulic brake fluid
• Shim-less mounting bracket allows for quick installation and setting up
• Recommended for use with Ice Tech Freeza Centre-Lock SM-RT800 rotors for optimum braking performance
• Comes complete with resin compound aluminium radiation fin pad further improves heat dissipation reducing
  brake surface temperature by 50 deg C
• Inline hose routing for low profile design
