Durable centerlock to sixnail disc adapter designed for MTB hubs — lets you fit sixnail discs to center lock hubs while delivering reliable, longlasting braking performance. Key benefits Built to last: Made from strength, antirust materials that resist deformation and corrosion for consistent performance over time. Smooth, precise fit: CNC machining produces a clean finish that reduces abrasion and ensures accurate alignment with your hub and rotor. Fast and simple installation: Designed for quick mounting on center lock hubs; follow the installation requirement that includes a center distance of 44mm between the sixnail disc and the hole. Reliable braking: Provides a stable, precise interface between your center lock hub and sixnail disc rotor to maintain braking responsiveness on MTB rides. Features and specifications Function: Adapter for mounting sixnail (6bolt) disc rotors to center lock hubs. Material: strength, antirust construction for durability and corrosion resistance. Manufacturing: CNC machined for smooth finish and precise tolerances. Installation requirement: Center distance of 44mm between the sixnail disc and the hole. Compatibility: Specifically suited for MTB cycling and center lock hub systems. Installation notes Confirm your rotor follows the sixnail pattern and measure to ensure the center distance of 44mm as specified. Mount the adapter onto the center lock hub, align the sixnail rotor to the adapter holes, and fasten according to your rotor and hub manufacturer torque recommendations. Designed for straightforward fitment to reduce installation time and alignment adjustments. Practical use scenarios Upgrading a wheelset: Fit aftermarket sixnail rotors to a bike with center lock hubs to use a preferred rotor model or brand. Trail maintenance and replacement: Swap out corroded or damaged adapters quickly during routine maintenance to restore secure rotor mounting and braking performance. Bike build or : Use when assembling or converting an MTB to accept sixnail disc rotors while retaining center lock hubs. What makes this adapter stand out Combines antirust, strength materials with CNC precision to deliver a robust, accurate adapter that minimizes wear and maintains alignment under load. Clear installation requirement (44mm center distance) helps ensure correct setup and predictable compatibility with sixnail rotors and center lock hubs. Compatibility reminder Intended for MTB use with center lock hubs and sixnail disc rotors. Verify rotor pattern and the specified 44mm center distance before and installation.
