http://ebay.com/<blah I suppose these are the very rare early version, but I find this selling price remarkable. I know, I know, it's Ebay and all, but given the essentially useless images and the reputation that these hubs have for failures (stripping splines?) why would people bid so aggressively? I suppose the bidders may have had more info than was on the auction. Another thing: did bi-valents ever actually get used for actual racing? Bivalents and M-71's are both groovy examples of Cinelli innovation that never really caught on. I wasn't riding in the early 70's but aren't these both items that were used by the tech-weeines of that day, items that never found favor among racers?

I like the design of the bivalents, but have been careful with mine. Like avoiding big freewheels, so I can't overtorque them (at my age?). One series was 3-piece (steel barrel, alloy flange). There are also one-piece alloy units. I don't know if both series had stripping problems. I do have a friend who started with two sets (4 hubs) and gradually reduced them to nono-valent: 3 fronts and one rear...

Your mileage may vary, but it was a great concept. Don't have to shift gears to change wheels, since the FW part stays on the frame. Even included a little "Y" that bolts to the little tube connecting the chainstays, to make placement a bit more automatic!
