This is a cateye heavy-duty wiring harness for many of their bicycle computers. The wires are extra thick on this model to prevent breaking. This kit includes the harness itself, all necessary clamps, wheel magnet, shims, zip-ties, and the instructions. Add a computer to a second bike, or replace your damaged harness. $5 is a great deal for a new heavy duty harness.
