Product Information

The Shimano 105 ST-R7170/BR-R7170 Hydraulic Disc Brake Set is a solid choice for road cyclists seeking reliable stopping power and the precision of electronic shifting. This system brings Shimano's proven hydraulic braking technology and Di2 electronic shifting to the accessible 105 groupset, offering a substantial upgrade in performance and rider control. You'll notice the crisp, fast gear changes and confident braking immediately.

The BR-R7170 calipers are engineered for consistent performance, featuring a low-profile flat mount design and a 10% wider pad clearance. This wider clearance helps reduce rotor rub and contributes to quieter operation, even in less-than-ideal conditions.

It's truly built for demanding road conditions and spirited riding.
