Shimano Dura-Ace BR-R9270 Caliper freni a disco ruota posteriore Flat Mount

With an all-new design, DURA-ACE BR-R9270 hydraulic calipers are our most compact yet. With an all-new MONO-BODY construction design, high performance braking has reached a new peak. The BR-R9270 caliper drops weight while also providing increased pad clearance, ensuring a quieter ride. Lastly, a new bleeding process makes maintenance easier than ever.

ONE WAY BLEEDING
“ONE WAY BLEEDING” was developed for quick and easy prevention of air in our hydraulic system. Shimano has 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.
