Shimano 105 R7120 Mechanical Disk Groupset - 2x12-speed
105 R7100 – Pure Premium Mechanical Shifting
In the version as a 12-speed shifting system, the mechanical 105 group relies on the tried and tested. With the deliberate renunciation of the use of software, it represents a tribute to the purest form of road cycling. Craftsmanship and inventive spirit meet pure shifting pleasure for the adventures mastered under their own power.
Inspired by the electronic Di2 equivalent, the mechanical shifting groupset also offers a large gear range and a low gradation. This not only allows you to climb any mountain, but also to master any road at high speed. According to Shimano's "Science of Speed" philosophy, ambitious riders get maximum performance at an attractive price with the R7100 components.
Composition of the Shimano 105 R7100 groupset:
- 105 ST-R7120 | brake/shift lever (STI, left + right)
- 105 BR-R7170 | disc brake caliper (hydraulic, Flat Mount, front + rear)
- 105 FC-R7100 | crankset (HOLLOWTECH II, 50/34 teeth)
- 105 FD-R7100 | front derailleur (braze-on or clamp)
- 105 RD-R7100 | rear derailleur (Shadow RD)
- CS-HG710-12 | cassette (HG-L2 / HG-EV compatible, 11-34 teeth)
- SLX CN-M7100 | chain (incl. Quick Link chain connector)
- SLX RT-MT64 | brake disc (Centerlock, 160 mm, 2 pieces)
- BB-RS501 | bottom bracket threaded BSA (English)
Hubs are not included. These can be ordered separately.
Mechanical perfection. With the mechanical 12-speed components of the 105 series, Shimano offers a shifting system for the most diverse types of road cyclists. However, the ST-R7120 shift/brake levers not only feature the fast and intuitive shifting quality typical of the series, but also know how to impress on an ergonomic level thanks to improved grip and optimized comfort features. Meanwhile, the hydraulic BR-R7170 brake calipers offer a natural deceleration feel with which athletes can test their limits even further.
The FC-R7100 crankset relies on Shimano's proven Hollowtech II and Hollowglide construction methods for both the crank arms and chainrings to create a lightweight yet stiff drivetrain component. This combination allows not only an efficient power transmission, but in conjunction with the front derailleur and rear derailleur a responsive but also harmonious, consistent and at the same time natural shifting behavior. While the RD-R7100 rear derailleur comes up with the proven Shadow RD design, the FD-R7100 front derailleur convinces with its simple and precise adjustability.
