Is the Wolf Tooth Internal Spline Lockring Right for Your Frame?

The Wolf Tooth Centerlock Rotor Lockring Internal Spline was designed specifically for frames and forks where tight clearances prevent the external spline version from fitting. Its slim-profile internal spline design creates more room between the lockring and the chainstay or fork leg, opening up compatibility with tighter modern frame geometries. Available in six anodized colors to match other Wolf Tooth components across your build.

Made from 7075-T6 aluminum and machined at Wolf Tooth's facility in Minnesota, USA, this lockring delivers the same precision and durability as the external version in a more compact package. Compatible with 12mm thru axles and quick release, it suits most modern road, gravel, and mountain bikes. Sold individually so you can spec the exact color and quantity your build calls for.
