Chris King makes its own angular contact bearings; stainless steel standard with a ceramic upgrade, user serviceable with the King injector tool. List price is the chrisking.com US price for the stainless steel bearing version in standard colors ($215); ceramic bearings are $325, and the Matte Gold 50th finish costs more ($245 stainless steel, $355 ceramic). A Fit Kit is included in the price. First year is the chrisking.com store listing date (published 2023-03-29). msrp_usd is the launch year price: a September 2023 capture of the product page shows $212 for stainless steel and $322 for ceramic, with no compare at price. Fixed 2026-09-27: the special finish note now matches the live chrisking.com variants (only Matte Gold 50th carries a surcharge, $245 or $355; no Two Tone Black Punch is offered), replacing the unsupported $245 to $385 range.
