Sorry, I should have said "mileage"
You could also if you wanted turn your plain speedo into a cadence counter, but not at the same time as it is a speedo. One or the other only.
Search for it on Google or Youtube IIRC there's lots of videos. The distance you can put the transmitter and receiver apart will depend upon your computer and any other inteference; experimenting is the only real answer.That's an interesting idea. I'd quite to know my cadence (but not enough to buy a new Garmin that will do it).
Have you done it?
Does it work with the speedo on the bars, or is that too far away? (Presumably, you have to put the stationary part of the sensor on the chainstay.)
I goes on the non drive side of the chain stay, so that you get speed and cadence.aww balls, not reading properly
he has the garmin sppeed sensor located on the frame parallel to the rear wheel.
So change my answer to "I dunno"
