Hey everyone. Gonna be building my hardtail pretty quick and was doing some tool shopping as I needed a couple tools to assemble the entire bike myself. Anyway, found a disc mount machining tool on Park's website and they say it's essential for proper brake performance. I've NEVER heard of anyone machining their mounts, although it sounds logical. Is it more of a repair tool instead of something you do to a new frame? My frame is new, I shouldn't need to do this, right?
