The third brake lever allows braking while remaining in the aero position. It mounts onto the existing aerobar shifter mount, the lever attaches to the shifter with included hardware. The third lever kit does not affect use of existing brake levers. A cable splitter mechanism installs inline on either the front or rear brake and lets you use either your bar or extension mounted lever.
Includes all hardware for mounting onto existing barcon shifters and cable splitter. Specify campy or shimano. Weight: not much.
