https://www.amazon.com/dp/B085DBKLSQ?ref=ppx_pop_mob_ap_share I just got this one. It’s working great.
Thanks. Apparently that company will not ship to the US. I found a generic HRM replacement band on ebay that claims it will stretch up to 61 inches. Hopefully I can squeeze into that, and hopefully in a few weeks my size will be down some.
I later found another generic option that claims up to 61 inch stress cheaper on Amazon should anyone else need one. https://smile.amazon.com/Heart-Rate-Monitor-Replacement-Strap/dp/B085DBKLSQ/ref=sr_1_6?crid=2KFR36Z2LVWAT&dchild=1&keywords=wahoo+tickr+heart+rate+monitor&qid=1619127381&sprefix=wahoio+t%2Caps%2C154&sr=8-6
When my Tickr strap failed, I got one of these: https://www.amazon.com/Heart-Rate-Monitor-Replacement-Strap/dp/B085DBKLSQ/
It has been solid ever since. Cheap and quick fix — and if it doesn't solve your issue, you have a backup for when your Tickr's strap inevitably fails.
