I picked up what appear to be some very nice wheels. They're great arya silver silky finish rims with reinforced eyelets laced to shimano hubs. The hubs have oil holes and black clip covers. They seem to be early shimano hubs, could they be early dura ace hubs? What shimano hubs came with oil holes? What's odd with these is that cluster on the rear wheel seems to be a cassette rather than a freewheel. It's an early cassette as there does not appear to be a lockring, rather the first cog seems to fill that role. When did shimano introduce the cassette? They're great wheels, look almost NOS. I think they'll find they're way onto the lady of the house's trek mixte.
