Thanks guys! I like the Vetta...since I have it, you know? I hadn't thought of mounting the mag on the chainring, will give that a look. The cadence sensor should be plenty long, but I will have to splice in some wire to extend the speed sensor, I'm pretty sure. Is there any benefit to putting it on the rear (26") wheel as opposed to the front (20") wheel? I know how to do a rollout, so that's not a problem, just curious if there's any difference.
