what's your bike:wheel ratio?
For road bikes, mine is currently 2:3. 2 pairs of carbon clinchers and 1 pair of tubulars for racing. I don't like to have stuff, so I'm considering getting rid of the tubular because it doesn't get very much use, and two pairs of wheels are plenty as far as backup wheels. On the other hand, my tubulars are 300g lighter than my lighter clincher set (tires included). I don't know if that's a real advantage or not. Looking for wisdom.
