late 90s cannondale r1000 builtup help!
 

Hi, I just picked up a used r1000 frame off craigslist. I'm not sure the exact year it was made, but it has Campy veloce brakes and front derailer with the frame. However, I'm not sure what parts I need to rebuild it. I'm not sure how what size cassett the rear was designed for, and also if the front is a double or triple. Also, how do I know which shifters will be compatable with this setup. Any help would be appreciated! thanks!
