Bought a right lever mech after talking with Support Manager, Mitchel S. He provided more info and assurance that I was buying the correct part; it came a few days later. The lever comes complete with the sensor control wire already attached and sensor calibrated. The reach adjustment screw was set at the perfect the distance. Replacing the lever was pretty straight forward. I bled the line as well to remove a small amount of trapped air. The lever performs flawlessly and the braking performance is like the day I bought the bike. Very happy with the customer support/service and confident in braking again.
