The new DURA-ACE BR-R9270 hydraulic disc brake caliper has a refined brake caliper design, delivering a quieter brake system. The new brake calipers boast a 10% increase in pad to rotor clearance to reduce noise while a separate bleed port and valve screw improve the bleeding process so that it’s now possible to bleed the system without removing the caliper from the frame.
More fine-tuned control and heightened braking performance, thanks to SERVO WAVE Technology allowing for a faster initial bite point followed by a wider control area
13% wider control area from the brake lever
