Bought a Trek 7.3 FX on 5/5/10 ($600) and have spent more than twice what the bike cost me. Have ridden more than 1,300 miles in that time frame. Cost per mile still over $1 per mile. Running is a lot cheaper for sure.
Lights: Exposure Toro-- handlebar/Joy Stick(helmet)--2 red Eyes. Dinotte 400 tailight. MS900--handlebar and a SP flasher. Edison would wet his pants if he saw the display. Awesome in the dark and very noticeable during the day(flash mode). Animals cower. A snake was crossing the road a few early mornings ago (0500) saw the lights and shed its' skin!
Bike gear: pedals/'puter/seat bag/handlebar grips/shoes.
Clothing: Several Primal jerseys and shorts. Pearl I PRO shorts. Some more bike Jerseys. A couple of helmets--you know match the outfit. Numerous pairs of bike gloves--match the outfit. I already have a Garmin 305 HR monitor from my running as well as head sweats,socks etc.
I am glad I didn't buy a $2-3K + bike. God knows what I would have to spend. Nick
