With an all-new design, DURA-ACE BR-R9270 hydraulic calipers are our most compact yet. MONO-BODY construction ensures light weight and rigidity, proving that good things can come in small packages. 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.
