Phat,

only problem you may have with new components on your Older frame is the drop out spacing at the rear. older frames used 126mm spacing. Newer frames are 130mm.

May not sound like much but theres enough additional preload on the hub bearings to cause premature wear. YOu may need to widen the rear stays.

For the purposes you going to use the bike it more than adequate, In fact I'd like Veloce on my commuter! I've got a mix and match of Shimano from the late 80's and early 90's on mine.
