Campagnolo systematically expanded their product line through the decades to 1968, where they introduced brakes, yes in very small quantities but that set the plate for complete ensembles from one manufacturer. Shimano did later begin to offer even more, freewheels and chains, freehubs and even stems, rims and wheels, components Campagnolo later included or continued to avoid.

It is interesting now that the full ensemble manufactures moved into complete wheels and reduced their presence in seatposts, headsets, pedals. Often still made but not market demanded or expected.
