DT Swiss Dual-Spline Universal Centre-Lock Lockring

- Dual-spline universal lockring for Centre-lock hubs
- For 12mm or Q/R hubs use the inner spline with a standard HG cassette tool
- For 15mm MTB front hubs use the outer 'BB' style spline
- Low profile outer spline for tight clearance forks and frames such as those found on some aero road designs
- Whilst not essential, we advise that you use an aluminium tool such as the Park BBT-69.2 to prevent unsightly marking to the ring's splines on installation
- DT Swiss recommend using a torque wrench set to 40NM when installing
