I am going with a new Shimano m629 hub and I have to use a rotor adapter since I am going to keep my 6 bolt Avid rotor. I found two rotor adapters, but not sure if one is any better than the other. Does anyone know if they are the same or different? Any recommendations? I wanted to stay with the same manufacturer to help with compatibility.
