so i just picked up a 2001 GT ZRX off of craigslist. great price and nice build, on paper. im having a hard time getting the thing to fit right and wonder how cross geometry differs from road bikes. i get the premise of a more slack seat tube but it just seems to fit wonky. my back feel great, and the reach to the bars is excellent, but my knees feel squashed in front. the seat height is approximately right, maybe a little higher but the seat feels like it needs to go back. perhaps move it back and get a shorter stem? its an odd sensation to explain but it seems like the top half of the bike is sized long, while the back half is too short!
