As mentioned, the Vitamin T was a hardtail MTB. Their previous road bike was the Orange Dynamo.
A Cannondale CAD 10 equipped with 105 is a bike with issues. Specifically, Cannondales BB convention means a BB that grinds, clicks and squeeks you to distraction – at least in the British climate. Their integrated headset bearings are about as well sealed as an open window, and fills with grit quicker than a budgie gizzard. The bearings sit directly in the frame, something I think Is A Very Bad Idea.
My point is that Cannondale are sometimes a bit shit and cheap, and do a good job of trading on their past.
Of course, I know nothing about this CarbO thing, It may have these problems and more, but the point is, there are cheap carbon bikes with 105, and expensive carbon bikes with 105. Extreme point, you could build up a Cervelo R5CA with 105 and have no change from 10K.
