I have used a regular Campy Veloce with a Capreo, and it appeared to work fine. I did that for about 9 months. Then saw a good deal on a Capreo derailleur and switched it out.
I've never even seen a Capreo derailer.
I thought that it was designed with a single chainring in mind, a shorter tension pulley, and more clearance with the ground.
Notice the low capacity. But see the aforementioned sentence before putting too much weight into the statement. I wouldn't put it past Shimano to simply label the capacity at the Capreo default rather than a true maximum.
