Hello. I got these large flange dura ace hubs at the weekend. Am I right that they may be 1st generation? If they are not how old are they. QR nut on rear is actually campagnolo.
Thanks

H series.... Shimano a bit slow on doing all black stuff in Dura Ace guise, they "forgot" to do a black Dura Ace rear mech so it launched with the black Crane to finish the group. 1974 if memory serves?

i had some of these but in the small flange version. I was forever breaking rear axles at the point of where the block-side cone ends. In the end I got some campag record axles and threaded those cones and locknut onto it. Needless to say, the threading was slightly different, but I forced it on (obviously recutting a thread) and never had another snapped axle.
I see your rear hub is also missing the chrome locknuts.

nice hubs though

Nice hubs, always been a sucker for an LF hub and I'm sure I've got the mechs in black to go with those somewhere.

Thanks for the replies. I thought the locknuts/spacers on the rear did not look 100%correct but bought them off FB from photos and got a mate to collect. Front spins very well. The rear spins okay but I think would benefit from a service.
