Ashima Centerlock Adapter

Designed to expand rotor compatibility, the Ashima Centerlock Adapter allows the use of standard 6-bolt ISO disc rotors on hubs equipped with the Shimano-type Centerlock interface. The adapter is constructed around a steel main carrier with aluminum plates and locating pins, giving the assembly a balance of strength, alignment accuracy, and low mass.

Weighing approximately 27g per wheel, the assembly accommodates a wide range of axle standards—from 9 mm QR to 20 mm thru-axle—making it suitable for road, gravel, and MTB applications. Installation is straightforward: position the rotor onto the adapter, seat the adapter onto the hub’s Centerlock spline, and tighten the threaded lockring using a Hollowtech II–style bottom bracket tool. For secure operation, torque the lockring to 40 Nm.
