Gearing options include an 11-34T and 11-36T cassette paired with the FC-R7100 HOLLOWTECH II 12-speed cranksets with 50-34T and 52-36T chainring options.

Designed to fit any hand size and shape, the ST-R7120 Shift/Brake levers provide a relaxed shifting experience with next-generation ergonomics for more comfort and control on the bike. The R7100 levers also feature a shorter reach – the distance from handlebar to lever – and offer lighter, smoother lever action for better braking control.
Braking is further optimized with the new Shimano 105 BR-7170 calipers that offer 10% more clearance with the brake rotor – meaning less rubbing and a quieter ride. The system is light, durable, and maintenance-friendly, with targeted innovation to simplify the brake bleeding process. SHIMANO 105 R7100 Mechanical is only compatible with hydraulic disc brakes.
