Don't plan on calling the wife for a SAG WAGON pickup when one is 30 miles from home. Flat tire, broken spoke, broken chain, blowout, fell in the ditch, etc.

And not enough tools to get oneself back on the road.

Explaining to the wife why there are 7 sets of dirty cycling shorts in the wash and you only went out riding once on the weekend?

Explaining why you have ripped trousers and cycling road rash when you were supposed to be working at home?
