Designed for road, gravel, mountain bike, and e-MTB enthusiasts, this adapter offers a lightweight, precision-engineered solution that ensures optimal braking performance without rotor wobble.

Troubleshooting
Rotor feels loose after installation
Check that the external lockring is tightened to the recommended torque specification using a proper cassette tool.
Rotor rubs against the brake caliper
Ensure the adapter is fully seated on the hub splines and verify that the rotor bolts are tightened evenly in a star pattern.

Verify that your tool is a standard external-style lockring/bottom bracket tool compatible with Shimano-style splines.

Setup, Compatibility & Care
Installation of the Galfer Centerlock adapter is straightforward for those familiar with standard bicycle maintenance. Ensure the hub interface is clean and free of debris before sliding the adapter into place. Align the 6-bolt rotor with the adapter holes, apply light thread-locking compound to the rotor bolts, and torque them according to the rotor manufacturer's specifications. Finally, use a standard Shimano-style lockring tool to tighten the external spline ring. It is recommended to periodically check the lockring tightness after the first few rides to ensure no movement has occurred. Clean the unit during routine bike washes with mild soap and water, avoiding harsh degreasers that may strip the anodized finish.
