Technologies

Mono-Body

• SHIMANO’s MONO-BODY caliper is machined from a single cold forged block in order to maximize stiffness. A perfect balance of stiffness and weight, the MONO-BODY caliper is a component of our linear response hydraulic disc brake system. Linear response equals strong power and superb controllability.

One Way Bleeding

• ''ONE WAY BLEEDING'' was developed for quick and easy prevention of air in 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.

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.

SCIENCE OF SPEED

• We take years to give you seconds. Speed was the driving force behind the new generation of road groups, and every decision our designers made was to make you faster. Shimano engineers worked to refine each component and every function to provide the best on-bike experience, whether you're sprinting to the finish on the Champs-Élysées or crushing your local climb.
