i've read some stuff here and there online regarding cannondale's sizing on their cyclocross bikes. one guy recommended downsizing by 4 cm (i.e. if you ride a 54cm road frame, buy a 50cm cdale cross frame). cdale's cross geometry page states that you should downsize by one size to retain the same top tube length as your standard size but get more standover height.
i'm eyeing a used 54cm 2005 cannondale xr1000 disc cross bike. i ride a 54cm felt f55. felt specs are very near in top tube length etc., but the standover height is what concerns me...giving credence to cdale's statement. the 2006 version of their cross bike lists a standover height of 82.3cm. my felt has a standover of 77.6cm. that's a big difference, esp during a cross race when you are jumping over the top tube all the time...
thoughts/experience with the cdale sizing? thanks!!!
