Campagnolo has always made nice hubs so I enjoyed overhauling and lacing these to Archetype rims. The rear hub needed help with pitted cones and sticky pawls but now it’s as good as new. The loose ball bearings were replaced on both hubs, which should be done as part of periodic maintenance. In the same way that regularly replacing your chain extends the life of cassettes and chainrings, replacing loose ball bearings saves your cups and cones. If you have nice hubs, take care of them and they will pay you back. Good hubs can last through several sets of rims — send yours in for renewal.
