I've never owned them but they certainly look high quality and classy, but I think that they are not the only game in town for really good C&V hubs. The Mavic 500 series sealed bearing hubs are held in high esteem too by many collectors/C&V riders. I have a set I laced on to GEL280 rims last year and I never had hubs that spin so smoothly and look and feel bullet proof!
