Just got back from my first road ride in San An, did a little over 30 miles. Those hills are something.
I've got an XXS frame for my bike. The tires are smaller than usual, 650C vs the more common 700C.
I'm short and kinda round. The two other women I were riding with are also short but not nearly as round as I am. They are not round at all, would say skinny, actually. Their bikes both have regular size tires.
Anyway, all things being equal, I would fly by them on the downhills. We had no clue why.
Is it my (uh) extra weight adding momentum to the downhill? Would having smaller tires have anything to do with it? Lower center of gravity?
