Wonky Wahoo TICKR HRM? Might be the strap…

After roughly three years of hard use, my original Wahoo TICKR gave up the ghost at the end of the summer. Given how well it had worked for me, I picked up a new, updated version without hesitation. This was August. The photo above shows the new strap on the left, and the older (replacement) strap from my original TICKR on the right which I purchased to troubleshoot my original TICKR. Notice anything weird there?

Yeah, it’s super corroded. And to make matters worse, it’s been cleaned several times over the last three months, and it always ends up looking just like that, or worse, after a few uses. Unsurprisingly, when it’s corroded, it doesn’t work very well as a heart rate (HR) sensor. When if first started happening, I thought all it needed was a firmware update, but that was only a temporary fix; probably because I also thoroughly cleaned the strap at the same time. The only thing that has really “fixed” it has been not using the strap that came with the new TICKR. The older (right) version is still corroding way faster than the original strap (which I still have), but at a slower rate (no idea why), so with some extra care and cleaning, it’s been doing OK.

Unfortunately, neither is a great long-term solution. And since, I suspect that Wahoo did something to the materials mix in the contacts on their newer straps because it’s happening on both straps, even if I get Wahoo to replace the strap that probably won’t actually resolve the issue.

HR straps are the bane of my existence. I had 1 Garmin and 1 TICKR die on me.

The TICKR died after 2-3 months. It never occurred to me to check the contacts. Thankfully I was able to return it to REI.

Now I have another TICKR that I got as a gift, and it’s been running fine, but I’ll be keeping a closer eye on the metal bits. I’ll have to research if there’s any solution that can clean up those terminals.

As we discussed previous, I also had to replace my longer term one. And that replacement was swapped out under warranty too. I checked mine (about 2 months old now) and I’m not seeing any corrosion yet. I haven’t done any maintenance. I know, gross.

Yours may just use or possibly Wahoo got a bad batch of snaps for a portion of their manufacturing.

Would love your thoughts, please comment.x
