Shimano BR-R7070 105 Hydraulic Disc Brake Caliper-Front

Shimano 105 BR-R7070 Hydraulic Disc Brake Caliper

Utilizing the current technologies of the Dura Ace R9100 and Ultegra R8000 road components, the Shimano 105 R7000 groupset offers added versatility and improved performance for a wide range of cyclists. The shifters are ergonomically refined and match the sleek design of their Ultegra predecessors, while the mid-length rear derailleur and 11-34 cassette expand the gear ratio range. The highlight of the new 105 is the expansion of the standard range with hydraulic disc brakes, which have the usual good properties of disc-specific Shimano components. The flat calipers are compatible with Ice Technologies pads and brake discs from a diameter of 140 mm to offer the most powerful Shimano 105 group ever.

Braking Performance & Thermal Management

The Shimano BR-R7070 caliper is engineered for stable braking performance during both short and extended rides. Its ceramic pistons reduce heat transfer to the hydraulic system, helping maintain consistent braking feel. When combined with Ice Technologies brake rotors and pads, the system efficiently dissipates heat generated during braking. This improves control on steep descents and reduces brake fade. The hydraulic system also provides smoother modulation compared to mechanical brakes, allowing riders to apply the exact braking force needed for confident and predictable stopping.
