Bianchi Cross Concept
 

I'm looking seriously at a Bianchi CC but have a couple questions. First. I'm about 5'10" but have a 32" inseam and am wondering if I should get the 55 or the 58 (I'm going to use the bike principally as a road bike, w/ a little off-road). I like the general comfort/geometry of the larger bike although it may be less than ideal for serious off-roading. Any thoughts? Any other thoughts/comments on alternative X bikes for consideration would be much appreciated. Thanks!

Sizing for 'cross bikes has been a very common post over the past few weeks - search this forum for details. Briefly, 'cross frames tend to run a bit big due to the increased height of the bottom bracket (for clearing obstacles). Most people on the forum have recommended trying one size smaller in a cross-specific frame as compared to a regular road bike. For example, I ride a 52cm road bike, but a 52cm cross-specific frame is way too big (standover is too high and top tube is too long). I ride a 49cm Bianchi Axis, which fits me well. Good luck.

i'm about the exact same size and was fitted for a 55 axis. i'd bet a 58 is too big.

Dude, with the money that you're spending for the Bianchi CC you could have a better bike. And from what I was told by other members here, the material that bike is made out of is not as durable as aluminum even.
