This is a like-new item, having only been used once on the front wheel for 50km. The reason I stopped using it is because I have a GPS-type cycle computer and didn't see the benefit of a speed sensor. The box, instruction manual, and silicone straps for installation are also included. The battery used during the single use is still inside, so I recommend replacing the battery before use. #CycleComputer #CycleComputer #RoadBike
