Ok, so my lock ring is deaded. Stripped. Me being stupid while drinking too many beers. I need to order a new one. What the heck do I need to order? I usually have my LBS order them, but since I'm in no hurry I figured I'd just order a couple online. The descriptions I keep seeing are "track cog lock rings." This isn't for a track hub though, it's for a bontrager mustang disc wheelset... What part do I need exactly? thanks!
