I have been riding with 9, 10 and 11 speed Campagnolo drivetrains for nearly 20 years so am very familiar and comfortable with their operation and ergonomics. The 11 speed chorus share the features I have always liked (comfortable hoodsbodies, precise repeatable shifting with great tactile feel, as well as independent braking, upshift, and downshift controls). These particular levers are part of upgrade to a 12 year old custom ti bike previously equipped with 10 speed Campagnolo drivetrain that has made it over 60k miles with only a minor refresh ($40 dollars of parts) to the shifters. I can only hope the newer parts provide the same level of durabiliity.
