Anybody have any idea what's going on? I have the cadence / speed transmitter installed and I had to kind of tilt it over to get the thing close enough to the crank to sense my cadence, which put the wheel sensor so close to the spokes that I had to flip the magnet around the other way. (the seat stays are curved a lot and run very close to the wheel)
I have an Edge 800, and the cadence sensor. Mine also cuts out like that, eg I'm doing 30+ mph down a hill and it'll show my speed as zero for a few seconds, or even minutes. To fix the problem, I'm using GPS for speed and distance, not the sensor. The downside is every now and then it'll report thousands of miles, because it thinks I biked from Seattle to Mongolia back to Seattle, in a minute or two, but this type of problem happens much less often than the cadence sensor cutting out.
I've owned every Oregon unit Garmin made, and every one of them had some important problem. It culminated in one of them, advertised as submersible waterproof, not working after I hiked in a rainstorm. Garmin makes very mediocre products. I put the cadence sensor on twice, verifying that it's alined properly and reads out, and I've had three bike mechanics look it over and tweak it if necessary. It isn't on wrong, it just doesn't always work.
The reason yours is reporting 5 miles on a 6 mile ride is that yours wasn't working 1/6 of the time.
PS - My max cadence is 223 rpm on each and every ride, according to Garmin. What an amazing coincidence!!
