Anyone have any ideas on using a Garmin Edge 800 on a Bike Friday? I would like to be able to adapt a cadence speed sensor.

As you probably know, the issue is that with the smaller rear wheel you likely can't position a GSC10 to pick up both a cadence magnet on the crank and a wheel magnet on a spoke. One thing that some have done is to remove the wheel pickup arm from the body of the GSC10 and extend the two wires so that they can attach it remotely. The wires are fine but if you have experience with this it's not an issue. Be sure to seal up the opening in the GSC10 where the wires go in.

If it's close enough, you may be able to fudge it by mounting the rare earth magnet on the rim (not on the brake track) and another on the very end of a crank arm, possibly extended a bit beyond the end of the arm if needed.

Garmin just released a new cadence sensor. It doesn't need a magnet and will work on any bike with more or less standard cranks.

Had that conumdrum with my Moulton APB.
I attached it for cadence and relied on auto to offer up my current speed.
I found the compromise fine despite initially worrying about accuracy etc.
A few rides and I never considered the "problem" again.
