This is cool. Enjoyed the description too:
The NBT2 is NOT suitable for use with super lightweight [stupid-liteTM] alloy racing frames, where the deraileurhanger already self destructs with normal use.
Prior to first time use it is recomended to check with conventional tools that the lockring hasn't been tightened way over the recommended torque by some hamfisted mechanic, to prevent overloading the dropout.
