Velox

Brand: Campagnolo

Entry-level Campagnolo rear derailleur (part number 2250), around 1970 (approximate dates). It belongs to the loose family of cheap steel drivetrains Campagnolo offered during its decades of dominance at the top end. A distinctive feature: the upper jockey wheel is concentric with the P pivot (rather than offset as on the Valentino), which gives it slightly more capacity; the curiously short-armed parallelogram appears to have been designed for 3- or 4-sprocket freewheels. 3/32 chain, friction operation, the era of 5-speed freewheels.
