I have a used Garmin HR Strap (old model, not the new comfort strap version) for sale as I recently purchased a Mio Link to replace it. Works perfectly fine and will be shipped with a brand new CR2032 battery. Looking to get $25

I also have a Garmin GSC-10 Speed/Cadence Sensor. I only used the cadence on this and decided to replace it with the new Garmin magnet free cadence sensor. Comes with sensor and both magnets. You'll have to source zip ties on your own. Looking to get $30 for it.

Thanks
