For sale is a used Campagnolo ErgoBrain bike computer. The computer comes with everything pictured. It is missing the cadence magnet. Cosmetically it is good with a scrape that you can see in pictures 3 and 4 at the 12:00 position on the computer display. We put in a new battery (included) and the display lit right up. I can't swear to it but the guys in the shop said it worked when they took it off the customer's bike a few years ago. It comes with an extensive owner's manual that covers all aspects of installation and programing.
