This happened several times, so I just went with the Wahoo speed sensor and mounted it on my front wheel axle, because I tend not to change my front wheel in a night. The reason why I went with the fork system to begin with was because I was using a tri-spoke, which is not the case anymore. If I return to a tri-spoke, I suppose I will have to re-think things. I still like the idea of a sensor that mounts in the valve hole.
