Shimano 105 R7100 2x12 34-50 Groupset

The Shimano 105 R7100 2x12-speed complete groupset - pure road cycling with first-class mechanics

With the 105 R7100, Shimano presents a mechanical 2x12-speed groupset for road bikes for the first time. Purist in design, it brings premium technology, high-precision function and unadulterated shifting pleasure to anyone who simply wants to ride a road bike, regardless of battery charge levels and firmware updates. The " Science of Speed" , which has already made Dura-Ace and Ultegra so powerful, is presented here at a particularly attractive price. The wide gear range lets you find the right gear for all occasions, whether you are riding on the flat or want to conquer mountains. You also benefit from perfect lever ergonomics and excellent braking performance thanks to disc brakes. The groupset includes a crank with 34- and 50-tooth chainrings, a cassette with 11-34 teeth, a braze-on front derailleur, a rear derailleur, a Quick-Link chain, two STIs and flat-mount brake calipers.
