the hands thing is kinda true - i'm definitely less in the know about bike maintenance than my hubs but i've tried to learn from him, his friend who bikes a lot and from free bike classes, but when it comes to changing a tube, i learned how to do it (by watching & instruction) but i haven't done it myself.

i can pump tires (which i do for my bike, our kids bike, and our bike trailer), and i will degrease the chain and re-lube them (hubs bike and my bike).

i kind of wish brakes were more sensitive to women's hands. gripping brakes definitely takes me more effort than hubs and our brakes are about the same. but my muscles are also just sore from riding, as much as hubs is sore.
