FEATURES - R-R9270 Disc Brake Caliper
J-Kit (Easy Hose Joint System): Brake systems with J-Kit hose joint the brake lever features an integrated olive what makes an easy brake hose installation and removal possible.
One Way Bleeding: 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.
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, 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.
TECHNOLOGY - R-R9270 Disc Brake Caliper
One-Piece Mono-Body Design - Not only does this design make the Shimano Dura Ace BR-R9270 brake caliper incredibly light, but also gives it outstanding stiffness values. At the same time, the Flat mount brake made from a single, cold-forged aluminium block proves that high performance is also possible with compact dimensions.
Increased Pad Spacing - A 10 % increase in brake pad spacing also allows for a significant reduction in noise during braking. In addition, when the RT-MT900 brake disc rotor (sold separately) is used, its deformation-resistant design, even with increasing heat, helps to create an extremely quiet and smooth braking system.
Easy Maintenance - To simplify maintenance, the hydraulic 2-piston brake caliper not only features the proven One-Way-Bleeding system, but also a separate arrangement of bleed nipple and opening screw. On the one hand, this minimises the risk of the bleed kit hose slipping off when opening or closing the system and, on the other hand, makes it unnecessary to dismantle the caliper from the frame for bleeding process.
