I used to mountain biking with the same bunch of guys every Saturday morning. They used to kid me about my somewhat "functional" equipment. My bike had a rigid fork and toe clips and I carried stuff like my helmet and shoes to the trailhead in a cardboard box. I can't really say that I ever dusted the other guys but I stayed up with them (kind'a) and we had a good time together.

A retrogrouch is a bike rider who lets the other guys waste their money trying out all of the new ideas.
