I've been casually looking for a CX bike over the past couple of weeks. I keep an eye out on ebay for good deals. Right now I'm looking at a Bianchi Cross Concept. It's a 49 cm. Based upon TT length I should ride the 49. Standover is fine too. However, there is no HT length listed on any of the sites i checked. I dont want to end up with a ton of spacers or too much of an aggressive riding position. Suggestions? My road ride is an Orbea Diva 53cm. I am 5'7.5" with 32" inseam (long legs, short torso)
