I haven't read all the responses here so if I repeat something already posted my apologies. A friend of mine has spent his life in the bicycle industry and raced locally. He calls my Guru Sidero (steel) "nervous." By which he means it steers very quickly. This is usually a result of fork rake and WB. Some would call it twitchy. My take on handling is that much, if not most, of it boils down to those two factors.....assuming similar wheels and tires.
