Product Information

Full details

The Shimano Ultegra R8070 Flat Mount Caliper is engineered for performance-focused road cyclists who demand consistent, reliable stopping power in diverse riding conditions. By utilizing oversized ceramic pistons and optimized heat dissipation technology, it provides superior control and modulation for high-speed descents. While it offers excellent braking performance, it requires a hydraulic disc-compatible frame setup, which may necessitate professional installation for those unfamiliar with internal fluid systems.

FAQs

Is this caliper compatible with my mountain bike?

No, this is specifically designed for the road-standard flat mount system.

Can I use DOT fluid in this system?

Absolutely not. This system is designed for mineral oil only; using DOT fluid will permanently damage the seals.

Does this package include the mounting bolts?

Yes, standard flat mount bolts are typically included, but please consult your specific frame requirements for length.

How often should I bleed the brakes?

Bleeding is usually required only if the lever feel becomes soft or after extensive service, such as shortening the brake hose.

Can I upgrade from 140 mm to 160 mm rotors?

Yes, by adding the correct Shimano flat mount adapter, you can safely run 160 mm rotors.

Troubleshooting

Brake lever feels spongy or soft

Perform a one-way bleed to remove trapped air from the hydraulic circuit.

Constant rotor rubbing noise

Verify the caliper is centered over the rotor and check that the pistons are not stuck by cleaning them gently with a non-abrasive tool.

Reduced braking power

Check the thickness of the brake pads; if they are below the manufacturer's recommended limit, replace them. Clean rotors with isopropyl alcohol to remove contaminants.

Pros and Cons

Pros

  • Excellent heat management with cooling fin pads
  • Reliable and consistent braking modulation
  • Reduced rotor drag due to increased clearance
  • Easy one-way hydraulic bleeding process
  • Durable ceramic piston construction

Cons

  • Limited to flat mount frame standards
  • Requires specific hydraulic fluid compatibility
  • Not intended for non-hydraulic road systems

Setup, Compatibility & Care

This caliper is designed exclusively for the flat mount standard found on most modern road disc frames. It comes pre-configured for 140 mm rotors, but can be adapted to 160 mm rotors using the appropriate flat mount adapter bracket.

Compatibility Requirements:

  • Fluid: Must use Shimano genuine mineral oil; do not use DOT fluid.
  • Mounting: Flat mount road disc frames only.
  • Maintenance: Periodically check for pad wear and ensure the rotor surface is clean. If you notice a 'mushy' lever feel, perform a one-way bleed to clear trapped air from the hydraulic line. Always use an isopropyl alcohol solution to clean the rotors of any oil residue to maintain peak performance.
