- Measure speed to 1/10 kph
- Must be wired (wireless has too much lag time for measuring sprints)
- Must work on rear wheel for trainer use
I finally found a solution. The new CatEye Strada, mounted on the top tube.
I can't see it while I'm riding, but all I really care about is max speed at the end of a sprint.
If anyone has any other solutions, let me know. I just made $0.36, so I'm well on my way to being able to buy another computer.
