Nope. On the drive side, it's attatched to the only hole on that dropout. That one is threaded and it worked with the included hardware. On the other side there are 3 holes. The one in the middle is threaded for the correct size and that's the one I used originally. The other two holes are larger and aren't threaded at all, I'm using the one closest to the front of the frame. Does that make sense? I don't know if it matters, but it's a circa 2000 Gary Fisher Tassajara mtb.
