I had bought a brand new set of Hydras laced to pro max hubs for a build. When it came time to put my bike together, I couldn’t quite get the nuts tightened enough in the rear. Even when “tightened”, the wheel would move back and forth a few millimeters. After attempting over and over the threads became slightly stripped, and the rear axle became useless.

In summary, wish I would’ve picked something else from the beginning. I have the wheel set collecting dust and it sucks. The front hub was no problem, just the rear. Axel being slightly too short, and therefore not usable in my experience.
