Regarding the center-lock interface on the Chris King R45D rear hub,

↑(the split isn't visible in the photo)
You have to remove the split cone from the hub axle,
remove the cone locknut,
then secure the disc rotor with an external-lock lockring,
and finally reinstall the cone locknut and split cone—
a somewhat tedious procedure, as I mentioned the other day.
Well, Chris King has now announced they'll be releasing
an external-lock lockring
(the front hub can use a standard internal-lock ring normally,
and partial hub disassembly isn't necessary).


This blog's policy is to avoid self-shot images when possible,
but since this is a new product that hasn't arrived at distributors yet,
I can't photograph the actual item.

The lockring with white "KING" lettering
has a suggested retail price of ¥5,280 including tax,
while the two-tone black lockring with matte punch (a pinkish shade)
or gold lettering in the center
is priced at ¥6,930 including tax.
I guess the price is justified because they match the anodize color of the hub.
