SHIMANO 105 DI2 ST-R7170 Shifting lever
Shimano has again collaborated with professional riders in the development of the electronic 2x12-speed control units of the 105 series. Not only that also a Wireless system has found its way to provide a tidy and wonderfully minimalist cockpit, also at the ergonomics was extensively tweaked. Characteristic of the revised aesthetics and aerodynamics are above all the raised lever hoods, which prevent fatigue regardless of the hand position and ensure first-class comfort. SHIMANO 105 Di2 FD-R7150 FRONT DERAILLEUR The introduction of the Di2 shifting system in components of the current 105 series also ensures the FD-R7150-12 front derailleur that gear changes are even more precise and coordinated. The electronic shifting not only facilitates the change from the large to the small chainring and vice versa, but also reduces the risk of chain drops. SHIMANO 105 DI2 RD-R7150 REAR DERAILLEUR
Semi Synchro-Shift. The rear derailleur responds to the shifts made by the rider on the front derailleur. In doing so, the rear derailleur automatically provides the necessary compensation shifting for low cadence jumps when shifting up or down at the front derailleur. SHIMANO BR-R7170 CALIPER
Thanks 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. ERGONOMIC HOLLOW SADDLE
The hollow design saddle, reduce crotch pressure, decrease heat as well , less burden for long tour cycling. SHIMANO 105 FC-R7100 CRANK
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.
