I installed a CatEye MC100W wireless cyclometer tonight. Nice model -- groovy backlight. Naturally, there are more options on this thing than I need, but I'll survive. Since the bike is new, the odometer will be pretty accurate. I'll be able to know how many freakin' miles I've put on the bike in the course of a year. I realize I may be the only one excited by that right now, but I'm having a party, and any one of you can join me whenever you like!
