Max - maybe I'm misunderstanding your intent, but while the Paul site does suggest the Racers are designed for direct mounting (the center mount adapter plate is optional), direct mount centerpulls can't be used on cantilever brake posts. For one the positioning for centerpull brake pivots and cantilever brake posts is different (centerpull pivots are above the rim, cantilever / v-brake posts are below the rim). These days there aren't too many non-custom frames that have centerpull brake mounts, it's more common to use centerpulls with a plate for central mounting like a standard road caliper brake.
