Is there a big noticeable difference between the two on longish type road rides? I have a Kona Jake that weighs in at around 23 lbs. It has 25mm Conti slicks on it. My last road bike was a Specialized Allez Epic carbon fiber that I sold years ago that I think weighed in at around 21 lbs. Although the Jake is only a couple of lbs heavier, it just seems to be more sluggish out there on the roads. Maybe it's my imagination, but is there anything about the geometry of a typical CX bike that makes it handle differently on straight open roads?
