【CNC Precision Aluminum Alloy Construction】 Manufactured from high-strength aluminum alloy using CNC one-piece molding. Lightweight yet durable, with precise threading and alignment to ensure a tight, secure fit between rotor and hub.
【Wide Hub & Rotor Compatibility】 External Centerlock rotor lockring compatible with 9mm quick-release axles and 12mm / 15mm thru-axle hubs. Works with common Centerlock disc rotors including Shimano RT30 and RT54.
【Stable Braking with Accurate Torque】 Designed to be torqued to 40 N·m, providing even clamping force across the rotor. Helps reduce rotor movement and minimizes the risk of uneven torque or brake vibration.
【Anodized Finish with Anti-Slip Texture】 Features a polished, anodized surface for corrosion resistance and long service life. The reverse-side anti-slip texture improves tool engagement during installation and removal.
【Professional Installation Ready】 Requires an external lockring tool such as a 44mm 16-tooth bottom bracket wrench (not included). Ideal for professional mechanics, bike shops, and experienced riders performing disc brake maintenance.
