It looks like the Cannodale Cyclocross bikes do have a higher bottom bracket. I read the article that was recommended, however, if you are considering a Cannondale, I'd recommend riding before you buy. I'm currently in the process of getting a cx bike. I ride a 56-58 size cannondale, but if you look at the standover height on the website, the 56 cx bike has a higher overall top tube height than even the 58 cm road frame. I might have to move down to a 54 to be able to standover the bike. So check the manufacturer before you buy if you can't ride the bike before purchasing.
