Shimano DURA ACE ST-R9120 2×11-speed STI Dual Control Set Gear Shift Lever 2 X 11-speed | Bike-Discount

With the introduction of DURA-ACE R9100, Shimano has reestablished the new benchmark for road performance by improving each component and incorporating its newest technologies. DURA-ACE R9100 delivers unparalleled performance, highly-refined ergonomics and immense customization to maximize every rider’s potential.

The introduction of hydraulic road disc brakes in the DURA-ACE lineup brings more control and confident braking in tough weather conditions. The hoods of the hydraulic levers (ST-R9120/70) are designed to incorporate the hydraulic reservoir and provide an ergonomic hand position, similar to the mechanical brake hoods (ST-R9100/50). 

Hydraulic disc brake calipers can be directly mounted on the frame (flat mount) for a clean low profile design. New dedicated DURA-ACE rotors bring better heat management properties to provide stability in brake performance. With an increased adaptor size, heat transfer through the rotor is decreased and more heat can dissipate through the air. This results in a 30°c reduction in rotor temperature over Shimano’s ICE TECHNOLOGIES FREEZA rotors.
