Wolf Tooth Crown Race Adapters

Wolf Tooth Crown Race Adapters Info

Wolf Tooth Crown Race Adapters provide a clean, precise solution for pairing forks with smaller steerer tube diameters to frames and headsets designed around a 1.5” lower bearing. Machined for accuracy and durability, these adapters allow greater flexibility when mixing modern frames with downhill, gravel, or specialty forks.

Many dual-crown suspension forks—such as the RockShox Boxxer or Fox 40—use straight 1 1/8” steerers, while some road, cyclocross, and bikepacking forks rely on a 1 1/4” lower steerer. In both cases, a properly engineered crown race adapter is required to interface correctly with a 1 1/2” lower headset cup. Wolf Tooth designed these adapters to maintain proper bearing alignment and steering smoothness without compromising strength or fit.

CNC machined from premium 7075-T6 aluminum, the adapter adds minimal weight while ensuring long-term reliability. Like all Wolf Tooth small parts, it’s built with tight tolerances and a no-nonsense approach to compatibility and performance.
