I don't think the OP is insisting on 37-47 reach brakes but wants to use Shimano calipers. What is not clear is why he referenced those Tektro 57-73 mm ultra long reach brakes if he doesn't need anything that long. If 47-57 mm reach is adequate, he has a lot of choices including at least two Shimano models.
