Bicycle Computer on the gpz

Julian, here are a couple pics, one of my cockpit with the Sigma BC800 and
another of the magnet epoxied to the rotor carrier and the pickup filed
smooth on the back and epoxied to the fork leg. I was going to suggest you
do the same but nothing would stick to all that crud! That's got to be the
dirtiest GPZ I've ever seen. Have some pride in your ride man!
