Shimano 105 R7100/R7120 Groupset 2x12-24 Speed - Brakes - Pure Premium Mechanical Hydraulic Disc Shifting

105 R7100/R7120 - 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.

The Shimano 105 R7100/R7120 groupset consists of:

• 105 ST-R7120 STI (left + right) W/Inner Cable
• BBR60 English Thread
• 105 BR-R7170 disc brake calipers resin ice-Tech Fin (Flat Mount front + rear) W/Housing
• 105 FC-R7100 crankset
• 105 FD-R7100 front derailleur(braze-on)
• 105 RD-R7100 rear derailleur(shadow RD)
• 105 CS-HG R7101-12 34T/ HG710-12 36T cassette
• CN-HG7100-12 chain

Also in the current 2x12-speed version of the 105 crank Shimanos proven hollow construction methods are used to enable not only a visually attractive, but also a lightweight yet rigid drivetrain component.While in the aluminum crank arms the Hollowtech II technology provides ample weight savings without compromising stability, the Hollowglide construction takes over this task in the large chainring, which is also made of aluminum. In addition, plastic ribs on the back of the chainrings stand for the unique structural design of the 105 series.

Shimano 105 ST-R7120 STI for hydraulic disc brakes

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 are not only characterized by the fast and intuitive shifting quality typical of the series, but also know how to convince on an ergonomic level thanks to improved grip and optimized comfort features.

A wide-ranging evaluation of different hand shapes and sizes has resulted in a modified grip positioning and a revised brake lever and clamp design. These adjustments have reduced the distance between the grip body and the brake lever, which in turn improves the leverage and provides more control with less effort. In addition, the brake/shift lever for 2x12-speed drivetrain systems is adjustable in reach.

Shimano 105 BR-R7170 disc brake caliper

hanks to the natural deceleration feel of the hydraulic Shimano BR-R7170 brakes, athletes can test their limits even further. While their flat profile makes the Flatmount disc brake calipers ideal for use on road bikes, a 10 % larger pad spacing compared to the previous model reduces the risk of unwanted brake friction and grinding brake discs.

This reduces overall noise during deceleration, but without compromising braking performance. On the contrary, the BR-R7170 calipers not only grip quickly, but also reliably. To keep the maintenance effort as low as possible, the proven One-Way-Bleeding system is used once again, combined with a simplified bleeding process, which makes it unnecessary to first remove the brake caliper from the frame.

Shimano 105 FD-R7100 front derailleur Direct Mount

With the mechanical 12-speed components of the 105 series, Shimano offers a shifting system for the most diverse types of road cyclists. The FD-R7100 front derailleur is characterized not only by a light, harmonious and at the same time natural shifting behavior, but also impresses with its simple and precise adjustability. In addition, the Down Swing front derailleur features the optimized cage design of the Shimano Toggle Link construction, which ensures seamless compatibility with road bikes with disc brakes with the help of various options for the cable control and thanks to an integrated adjustment option for cable tension.

Shimano 105 RD-R7000 rear derailleur

With the mechanical 12-speed components of the 105 series, Shimano offers a shifting system for the most diverse types of road cyclists. The RD-R7100 rear derailleur combines the harmonious, consistent and nevertheless responsive shifting behavior of the Shadow RD design with Direct Mount compatibility and a wider ratio range. Depending on the selected crankset and cassette, the Top Normal rear derailleur also enables energy-saving transmission with a ratio of less than 1:1, which is ideal for climbing and supports the rider when climbing even steep ramps.

Shimano 105 CS-R7000 cassette

The Shimano CS-HG7101 / HG710 cassette is optimally equipped for the most diverse terrain requirements. Whether sprints on the flat or steep climbs, with a gradation of 11 to 36 teeth, the 12-speed sprocket set has the right answer for every situation.

In addition to optimal acceleration, excellent efficiency when pedaling was at the forefront of the development, so that no energy is lost. While the 8 small sprockets ensure natural and comfortable transitions, the 4 large sprockets cover a wide range, but without accepting too abrupt changes in the gear ratio. In addition, the 12-speed cassette is also compatible with Shimano's previous 11-speed freewheel bodies.
