Hello, did you find any wheel sets that can accommodate your bike situation? I’m in the same boat with my Felt TT bike. It has that rear horizontal dropout with 23 mm max clearance. It also has the screws to push the wheel out slightly for some added clearance, but I don’t feel safe with it pushed out as any bump can pretty much push it back in.
I’m having zero luck finding deep rim wheel sets with 23mm outer width.
