Many brands offer brackets, wireless sensors and a variety of other spare parts for their bike computers. This can be very useful - not just in the event of loss or damage - but also, for example, allows a wireless bike computer to be used for several bikes with the help of a second radio sensor and, if necessary, an additional bracket. You'll also find alternative mounts to perfect your own cockpit and heart rate monitor chest straps or other sensors to use an optional cadence feature.
