I just picked up a used set of Mavic Ellipses. I just now went to take off the cog and swap it out, upon reinstallation of the lockring, I notice Formula etched into its side. My questions are, how close in thread pitch is the Mavic French threaded lockring to standard ones? Am I safe to continue using this lockring? Should I try to find a Mavic one at this point? The threads don't look amazing but it threads on nicely with no binding.
