105 R7100 / R7150 – It's A New Day

For the 40th anniversary since its launch in 1982, the 105 series gets its ultimate upgrade with Shimano's electronic Di2 shifting technology. Maintaining the series-typical price level, the precise shifting function, precisely tuned ratios and a reliable braking system thus become accessible to an even wider circle of road cyclists. Because in the tradition of its predecessors, the current 105 is also equipped with the top technologies – such as the wireless cockpit – and first-class features from the state-of-the-art Dura Ace and Ultegra series to enable their riders to discover the road anew, every single day.

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.

In its entirety, with the FC-R7100-12 road cyclists get not only an extremely lightweight, but also powerful crank, whose durable arms provide efficient power transmission. The crankset is completed with the thoughtfully designed chainrings which are perfectly matched to the FD-R7150 front derailleur and guarantee not only a fast, but also precise shifting behavior.

Hollowtech II

The guiding principle of Shimano's Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission. An exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve an optimum relationship between stiffness and low weight.
