Wahoo Speed Sensor mounting alternative - O-Ring?
When mounting the Wahoo speed sensor on my bike, I found that the asymmetrical hub on the rear wasn't really suited for a sensor to bridge the gap so I planned on putting it on the front, but the front hub is a smaller diameter than what Wahoo's OEM rubber mounting called for so it slipped around the hub. I trimmed the rubber latching portion off and used a standard O-ring around the hub. Mounted well and looked as good as factory, but in the week the bike sat there unridden the o-ring snapped.
Has anyone else had to adapt the sensor to a smaller diameter hub? I'm not displeased with the O-ring idea; I would just like one that was more pliable/less prone to breaking. Any thoughts?

How slender is your hub? I have a Wahoo sensor on my front wheel and I've had no issues with the supplied fastener.

It's entirely possible that the o-ring I purchased was older and brittle, because I can't imagine them being a frequenly restocked item at this hardware store.

I haven't measured with calipers, but the supplied mount from Wahoo was very loose. This small of a diameter is the only "downside" to Boyd's Skyuka hubs I've found.

Oh this one isn't approaching an inch in diameter.
Sadly it only came in one size. It could have been very simple for Wahoo to have done ladder rungs in the attachment to fit a wider range of hubs, but I guess this isn't that common of an issue.

Perhaps silicon O-rings work better than standard rubber.

Post a pic of your hub and how you are mounting the sensor. I too run the wireless speed sensor on the front tire and I had to stretch it to fit. That would have to be one skinny hub.

Why not get a strip of rubber to wrap around the hub (or anything to increase the diameter) and then install the sensor over that?

Have you contacted Wahoo support for a solution? It never hurts to ask. They were very helpful when the screen died on my Elemnt Bolt. BTW, my sensor is also mounted on the front wheel but I'm riding Zipp.
