I'm having trouble deciding size with this bike.

I found a 2006 Redline Conquest for sale, 58cm frame.

Just the other day I rode a 58cm Bianchi Volpe and it was perfectly fine.

Now I'm pretty sure these are both cyclocross, but i heard Redlines sizing is funny.

You think 58cm Redline Conquest would be fine?

Thanks.

check the specs. they look to be quite similar.
