Shimano 105 R7170 Disc Brake Caliper

Shimano BR-R7170 Flat Mount Caliper – Without Rotor

Offering 10% wider pad clearance than the mechanical 105 model, this flat mount caliper provides less brake rub and less noise. Perfect for pairing up with the Shimano 105 Di2 brake lever (available separately), it also delivers a simpler, maintenance-friendly brake fluid bleeding process.

Disc Brakes Optimised for Road Riding

With proven hydraulic braking technology, the Shimano 105 caliper features the Shimano Flat Mount System and its low-profile design that is ideal for road bikes. More compact and lighter than ever, the R7170 brakes offer wide pad clearance for easy wheel removal and quiet performance as well as one-way bleeding for easy, clean maintenance.

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 the Ice Technologies piston to realise the cooling technology for consistent performance. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss. This model’s Ice Technologies piston achieves optimised lightweight, high rigidity and heat dissipation.

One Way Bleeding

One Way Bleeding was developed for quick and easy prevention of air in the 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.

Shimano 105 Di2 brings electronic wireless shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, Shimano 105 Di2 represents a transformation of the road cycling experience.
