I'm curious what parameters make a bike stable, or shall I say, more stable. I mean the kind of stability that allows you to take both hands off your handlebars and zip up your jersey, or whatever. Like we could all do on our small ancient Schwinn's (or whatever) when we were kids. Yeah, I know all the guys in the TdF can do it, but they're athletes, and I'm not even close. So what things can help a klutz like me? Longer chainstays seem to be one item. Less "aggressive" head angle (I think that means a lower angle, like 71-72 deg, right?) seems to be another. What about bottom bracket height or drop? What about 650b rims and tires rather than 700c? What about fatter tires and/or tire pressure? What else?
Thanks in advance, Dick
