Hay I am 58 years old and have worked on everything from bikes, motorcycles, lawnmowers, big rigs, jets, and locomotives. I guess I just like thing to go easy now so I ordered the hub adapter and sprocket from Jim. It's a bummer working inside thoes spokes with my tired and artritic old hands. I'll bet he gets a lot of orders from people like me besides they sure do look better than the other setup.
