CatEye Cycle Computer This is a used MICRO WIRELESS CC-MC200W. I used it after purchasing it new, but I'm selling it because I no longer use it. Everything shown in the photos is included. I have confirmed its operation, and there appear to be no problems with power-on and communication measurement. (See the last photo) The CR2032 battery is included only in the main unit, but the sensor battery is not included, so please prepare one after purchase. - Model: MICRO WIRELESS - Functions: Speedometer, Odometer, Timer - Display units: km/h - Power source: Battery-powered - Accessories: Mount, Sensor, Strap Thank you for looking.
