Is a cross model the same as a road model besides the different chainrings? Thanks

yes they are all the same for hollowgrams you just change the spider or spindle lenght

Thanks, btw what is the difference between mk 3 and mk v rings? Is there any online stores that sell just the rings? THanks

Should I buy the cannondale spindle/bb? I got my hands on a hollowgram SL crankset off a cannondale superx bike and from the cannondale website, it states that the bb/spindle used is the FSA version.

Should I ditch the FSA stuff and get my hands on a proper cannondale bb/spindle? Even though I know the stock cannondale ceramic bearings that come on the bb/spindle is crap, I will prob upgrade to a better cermaic bearing set or use the FSA bearings that is paired with the FSA BB set on the superx. Thanks

the cannondale spindle only works with hollowgram cranks, fsa stuff won't work. you need a 104mm spindle for a double crank, along with bearing shields, shims and wavy washer

Well, the spindle that is with the hollowgram that i am referring to must be the hollowgram spindle then, from what you are stating. Strange, if you go on cannondale's site, and click on the superx spec, it states bb fsa, although it has hollowgram sl. Thanks

The spindle is part of the crank, not the bb. They probably just used FSA bearings in the frame.
