Your thought of moving to a disc compatible fork sounds like a good idea. If you were to do that, could you move the front brake to the rear by changing the pads and cutting and re-threading the mounting post? I was thinking that the campy brakes were dual-pivot on the front and single on the rear. As a aside, we have the Spyre's on our Co-motion and have had good luck with them. We have about 5,000 miles with only the front pads being replaced with the rears now needing replacement. Se live in Pennsylvania with hilly conditions but most decent being less than a mile.
