Doug Hack wants to expand the subcategories of vintage lightweight bicycles by distinguishing between criterium frame angles, road frame angles, cyclocross angles, and so on.
This could be a boon stimulate the market for collectibles by further rationalizing it. Creating more categories creates more possibilities for bikes to be the best. This stimulates bidding.
One question: do we really need to stimulate bidding right now? :-)
FWIW, market considerations aside, it makes good sense to me. Yes it will add even more arcanity to our collecting jones, but what is collecting without arcanity?
