Mainly looking for a 32H rear, but will consider a set if that's what you have. I'm not seeing these on the 'bay, other than the straight-pull version.

Very rare, since made only a very short time..7800-7801 were pooches..then 7850 short time before 7900..7900 almost identical. Ti FH body and all.

Thanks for the insight on the limited availability. I had some 7900 hubs and the engagement was clunky.

Interesting since the 7850 went back to the 2 pawl, FH body bolted to the hub body, system with 7850..and essentially the same as 7900. 7801/7800 had the loose 3 pawl, FH body type.

Weren't 7800 hubs an attempt by Shimano to Campify their freehub design? As you say, they quickly abandoned it and went back to their traditional design with 7850 and everything afterward.

Yes, almost identical in concept, just 3/16 bearing balls rather than 5/32..Unfortunately, shimano 10s(DA/Ultegra) cogsets ONLY..for the aluminum, deep spline, FH body. AND even more unfortunate, when they went to 7801..those small bits not compatible with 7800...and then 7900..back to TI FH body.
