SHIMANO Delivers Premium Mechanical Road Shifting with New 12-Speed SHIMANO 105 Groupset

For riders who love the feel and sound of Shimano’s crisp mechanical shifting, the new Shimano 105 R7100 12-speed groupset delivers premium performance features and updated ergonomics along with the simplicity of mechanical shifting. The lightweight SHIMANO 105 mechanical components offer reliable, easy-to-maintain shifting with a wide gear range so riders can pedal steady up climbs or focus on the winding road ahead without worrying about battery levels.

SHIMANO 105: Shifting Performance 

SHIMANO 105 mechanical 12-speed features the RD-R7100 rear derailleur infused with SHADOW RD technology. This offers a low profile and single-tension construction, giving riders a smooth, efficient, and silent performance. The new FD-R7100 front derailleur features toggle-link construction so riders can enjoy crips, reliable shifting, whether going up to the larger chainring or dropping down to the small one.

SHIMANO 105: Wider Gearing Range

With the jump to 12-speed, SHIMANO 105 R7100 delivers the high and low gearing ranges that riders want while offering a thoughtful gear-step progression for finding the right cadence on any terrain. 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. With more gearing options and a wider range, riders can climb more comfortably with an efficient cadence and still have big enough gears to prevent spinning out mid-descent or when sprinting on the flats.

SHIMANO 105: Enhanced Ergonomics and Powerful Control

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.
