[FWIW, the manager at the local Performance Bike store just off the trail says the Cateye has this problem.]

Anyone have experience with this computer, or alternatives with cadence, that seem to be less succeptible? (Or I'll just stick with my wired computer, although the Cateye has other features I like.) I'm curious about the Ciclosport and the Polar 720 (although I already have a HRM, it's more $ than I planned to spend, the cadence sensor is extra, and I would prefer a rear wheel speed sensor so I can also use the bike on my trainer).
