M22 Thread Adapter for Square Tapered & Splined Non-Extracting Crank Arms



This adapter is compatible with older and entry-level cranksets containing cranks arms removed with a crank puller (rather than integrated self extracting bolts). The adapter engages the M22x1.0 threads used by the crank puller when the crank bolt is removed. Once installed, features and use are identical to the Expanding Crank and Shimano Hollowtech II adapters

The pin extending from the adapter provides a stable reference point for VeloAngle to rotate between saddle and handlebar measurements. Because this measurement point is fixed and aligned with the crank axis, the saddle and handlebar adapter straps are not required to maintain tool orientation.
