This later style is better and easier to install and remove. My bikes came with an older style? that has a narrower width where socket fits on outside teeth, Ruined a brand new Park Tool socket. These later style have thicker metal on tooth area, about 4mm, where Shimano's older style has only a 2mm tooth thickness.
I do not know if the older style is new from China or up-grated by Shimano, The reason I stated this is that Lock-on rotors from China have thinner metal rotors and they have a one rounded side where they are stamped out of metal. Rotors from Shimano Japan have a flat surface on both sides and metal is thicker. So these rotor locks could be made in China and Japan, If so the ones with thicker tooth area must be from Japan, And the others must be from China.;

My order was fulfilled by Amazon via Pit Fall Cycles and I only received 1 locking ring. Other have said they received a 2 pack. Beware when ordering.;

I have R500 DB DT Swiss wheels with Shimano 105 hubs for my winter bike. I upgraded from 6 bolt rotors (with adapters) and needed lockrings. These fit/work without issues. The price should be for a pair and not a single lockring.;

Rotors can with internal spline lock ring. Tool wouldn't fit DT Swiss front hub. This fit perfectly and allowed for rotor to be installed. Will be ordering another so that rear rotor has same style lockring.;
