Lezyne heart rate flow sensor, free to a good home, brand new, never been opened. I cant use heart rate monitors because of my defibrillator but I picked up an ex-demo Macro GPS (which is a pile of pants) with monitor cheaper than I could get the Macro on its own. Refund whatever it costs to post (probably a couple of pounds) by means of first class stamps and it is yours.
If you want the Macro GPS too (as new) complete with a 3D printed adaptor to fit a Garmin mount make me a silly offer, you might be surprised how little I let it go for.
