Wahoo Tickr, Polar H7, Garmin HRM Coospo Heart Rate Monitor Strap Replacement (Powr Labs, M-XXL)

a lot of HRM devices use the same straps. I have/had 4 different brands of HRM devices, the straps are all interchangeable. The manufacturers themselves charge a lot of money for the strap, but there are some reasonably priced replacements. The actual bike computer doesn't matter in this case, the strap is dumb, it does not communicate (other than the electrical connection to the heart rate monitor device itself) https://www.amazon.com/dp/B085DBKLSQ
