Bicycle Lockrings

Ensure unyielding torque transfer and prevent component loosening under heavy riding loads with our Bicycle Lockrings collection. Serving as critical safety threaded retainers, lockrings lock rotating drive and braking components securely onto your wheel hubs. Choose from track cog lockrings featuring reverse left-hand threads designed to counteract counter-clockwise back-pedaling torque on fixed-gear hubs, cassette lockrings engineered with serrated locking faces to secure 7-to-12-speed cassette sprockets onto freehub bodies, Center Lock disc rotor lockrings available in internal tool spline and external bottom-bracket notch profiles for disc brake systems, or e-bike chainring lockrings built to secure spider interfaces to mid-drive motor axles. Manufactured from high-strength 7075-T6 aluminum alloys, heat-treated chromoly steel, and titanium, these precision-threaded retainers deliver maximum clamping force at low weights.
