So I take a magnet off the fridge to tape on to my Renn disk and wham, I'm doing 46 MPH on my trainer. WTF? Specs: Cateye Astrale 8 (with wires). Cadence is still correct with cadence magnet on crank arm. Any ideas where the problem is?
Side note- because of the bend in the chain stay (P2K), I had to face the speed sensor forward toward the front of the bike rather than backward, though I don't think that mattered. I had to do that in order for the sensor to pick up the magnet. Also, everything works normal on the stock wheel with its magnet.
Thoughts:Bad magnet (under powered)? HELP
