I picked up the Campy group in a trade a long time ago, from a buddy who had warned me the original rims needed replacing. The parts sat for a while before I decided Dyads might be good for a "road+" build on a Surly Cross Check. I put a lot of miles on that bike, both on and off pavement and they always felt great. Granted I only ever ran them with 700x42 Gravelking SKs I haven't tried the Dyads with any other tire, so I'm hoping they still perform well with 38 slicks.

Definitely going to squirrel away the R559s for potential 650b build down the road. I can see that being a fun "hey, I haven't done this kind of build yet" when there's a project lull. I initially disliked the idea of drilling the fork, but kinda warming up to it. I mean the rear brake bridge can accept a recessed nut so why not make them match. Also easy enough to use a plug if I decide to visit a retro build.
