General Information
This is listed as a Veloce Triple Rear Derailleur Model RD99-VL309 in the 2000 Campagnolo Catalog. The 1998 and 1999 Catalogs list it as a Model RD09-VL3. The 1998,1999 and 2000 Parts Catalogs show the same parts for both models.

These were designed to work with Campagnolo 9 Speed Ergo Power Brake/Shift Levers (brifters). The upper pulley has lateral float which allows the chain to self center on a sprocket making index shifting smooth. It also will provide index like shifting with friction levers.

The pulley center distance is 75mm which classifies this as a medium length cage rather than long.

The inner parallelogram plate and pulley cage are plated steel. This adds a little weight but provides for smooth shifts when making large jumps with wide range rear sprockets and triple cranks. Its rated for a 28T maximum sprocket but should be able to handle 32T without any problem.
