Description
Featuring a state-of-the-art design and all of Shimano's latest technologies, the ST-R9180 Dura-Ace Hydraulic Di2 STI Left Hand TT Lever is a top of the range option that delivers electronic gear shifts and hydraulic braking to high specification time trial and triathlon bikes.
The integrated buttons, one on either side of the lever, are linked seamlessly into the electronic Di2 system to deliver rapid gear shifts and heightened reliability. The gear changes are fully programmable via Shimano's Synchro Shift format, allowing the rider to tune the buttons' operation and the derailleur behaviour in line with personal preferences.
A hydraulic braking system that has a reservoir inbuilt into the lever body gives powerful and modulated stopping power and provides pad clearance auto-adjust so that the performance stays consistent throughout different stages of brake pad wear. The carbon brake levers keep the weight to a minimum and have reach adjustment so that all sizes of hands are catered for.
