Shimano MT805 cutting edge braking technology, lightweight and powerful easily adaptable post-style hydraulic flat mount disc brake caliper.
Upgrade your flat-mount XC bike with the new 2-piston R-MT805, appearance matched with XTR / XT.
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.
One Way Bleeding
"One Way Bleeding" was developed for quick and easy prevention of air in Shimano's hydraulic system. Shimano 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.
