This handle bar assembly is used with machines that are polar capable. This handlebar has holes for mounting the HR receiver under a plastic cover in the center of the handlebar. If you do not have a polar capable machine, you need to order 38000487.

NOTE: There was an upgrade to these machines a couple of years ago, and if your machine has 4 contact pads for heart rate, you need to order a new HTR board (38000196) to be compatible with the new 2 contact pad system.
