Not only are the brake mounts also the bolts that hold the brake to your frame, all in one, not a single tool is needed to adjust brake tension, no more adjusting springs or tedious centering, all the tension is managed through the sprung-steel straddle cable, AKA Springhanger. Just hook the Springhanger to you brake & you're done!
