Wahoo speed and cadence sensors
These do the job, but there seems to be a delay in reading the speed sensor. Also, it is super-difficult to get the speed sensor onto your wheel hub.
If you are watching the video and wondering why I am putting it on the back wheel, rather than the front, and making life more difficult for myself, it is that the rear wheel is the only one that spins on a turbo trainer.
