absoluteBLACK Centerlock Lockring Black, 15/20mm

What Our Gearhead(R) Experts Are Saying: "I swapped this in while building a lightweight gravel wheelset, and it's one of those small upgrades that makes sense immediately. It's noticeably lighter than stock, installs cleanly, and holds torque without any fuss."Details matter when we're refining a road, gravel, or cyclocross build, and the Ultimate Centerlock Lockring is one of those finishing touches that quietly elevates the whole setup. Designed by absoluteBLACK specifically for Centerlock disc rotors on QR and 12mm thru-axle hubs, it delivers secure rotor retention while cutting unnecessary weight from a place most riders overlook. CNC-machined from 7075 aluminum, the lockring weighs just 5. 8 grams, saving more than forty percent compared to many stock options. Its low-profile shape and precise spline interface make installation straightforward, while the refined machining gives it a clean, purpose-built look at the hub.
