i have a very excellent hewitt build ambrosio/sapim cx-ray on pmp 10-speed hub, campag 10-speed cassette (at present). upgrading to 11-speed cassette - err because it exists, and the 11-speed cassette locks on the hub.
i realise pmp make an 11-speed compatable hub but that is an expensive option with re-build as well
i have put question to DrD and pmp but as yet no answer. Any road cc bike pornographers have any useful advice?
thanks very much for any help. i cant find much through interweb searching.
