From Charlie Went Outside:
Mountain bike geometry is confusing. Head tube angle? Seat tube angle? Wheelbase? Standover height? Who cares! YOU care, because all of these things affect your ride. So I learned about them, and I’m going try to explain them in just 90 seconds. (Why? Well, the weather’s terrible for riding, so…this is what I’ve got. Fingers crossed next week is better!)
Simple, quick explanations. I like it!
