By reading the Road Cycling subforum on BikeForums, I get the impression a Fred is anyone with a practical bike, like commuters and utility cyclists. Also anyone with safety equipment like mirrors, reflectors, refective vests, etc. In other words, those of us who use bikes as more than toys.

While I do take the dork disks off all my bikes as soon as I get them home from the LBS (I keep my derailleurs properly adjusted, so no need for the plastic spoke protector), I left the reflectors on the bikes that are ridden at night. The climbing bikes are stripped down with no reflectors or fenders because they are daytime bikes for climbing hills, so performance is more important.
