Looks like there hasn't been much going on here for awhile, so I thought I'd give a try at getting some discussion going on.

I'm familiar with the Clydesdale & Athena definitions in the running context. Are definitions in the biking world any different? How?

Personally, I think the running definitions are cruddy because only weight is counted. A woman that is 5'8 & 145 pounds vs. a woman that is 5'1 & 145 pounds are two very different bodies.
