here's a special little gem I just received: a Campagnolo High-Low flange hub. I searched a little for extra info that I wanna share with you:
The high-low flange design claimed to made for stronger wheels, it shall counteract the different tensions due to wheel dish and help balance the spoke tensions from left and right (nds an ds sides). this was especially inportant as the rims of that era were typically low profile and not as sturdy as modern rims.
The claimed benefits were strongly debated, some say it made a difference, some say, its so marginal, there's practically no difference.
the earliest run of the campagnolo hi-low ( there were earlier ones made from Fratelli Brivio ) was made in the 70s. Here comes a little myth: it is said that Hugo Rickert, famous german framebuilder, has had a central role in convincing Campagnolo headquarters to actually manufacture the first batch of these hubs for the west-german cycling team, as they anticipated at first.
this would explain, why they never appeared in the catalogues of the 70s, they were a special order piece of eqipment only meant for the best.
The hubs were in the 1982 "olympic"* catalogue once and disappeared after that.
(* in preparation to the '84 olympics)
these infos are mainly from the retrogrouch blog and velobase.
the pictured hub uses the "crows foot" lacing pattern, another way of getting some more lateral stiffness compared to a 2x crossed lacing pattern.
