What Our Gearhead(R) Experts Are Saying: "I swapped my old lockring for the King Centerlock and immediately appreciated the smooth threading and secure fit. It stays put even on rowdy descents, and the anodized finish looks dialed with my headset. Classic King-overbuilt in the best way."The Chris King Centerlock Lockring is a small but mighty upgrade that reflects the brand's uncompromising commitment to precision. Crafted in Portland and made to exacting standards, this lockring does more than hold your rotor in place-it adds functional refinement and signature style to your setup. Designed to match the look and durability of King hubs, headsets, and rims, this lockring locks in both performance and aesthetic consistency. Machined from lightweight aluminum and paired with a steel crush washer, the lockring threads smoothly while resisting loosening thanks to specially shaped rear knurling. It fits any Centerlock rotor following Shimano's standard.
