I built up a wheelset from a pair of Goldix GDX 370 hubs a couple of months ago. I didn't have the bike frame to put them in, so they sat for a while.
Today I tried to install brake rotors for the first time on these hubs. I was PISSED when the very first bolt hole in the front hub stripped before I got to the spec'd 6.2 N-M torque!! I was even more pissed when a second bolt hole stripped.
I have a complaint in with the vendor. We'll see what happens. No matter what, though, I have to rebuild that wheel.
The rear rotor bolted on without incident, fortunately.
