A couple of tech questions for a guy returning to the road scene after a long layoff.

1) DA 7800 or 7900 chainrings: Do they work on any normal 130mm BCD spider? I use Cannondale Hollowgram cranks on all my bikes, have another set ready to go for this one, and want to confirm compatibility before I purchase.

2) Rim width: 23mm? 25mm? 27mm?

3) Rim depth: 38mm? 40mm? 50mm? 60mm?

4) Tire width: 23mm? 25mm? 28mm?

I'll be riding and racing on the road whenever I'm not racing my MTB. I live in VA during the school year, travel out west to CO during the summers. 65kg and I go up hills pretty well.
