Please refer to the following YouTube video: https://www.youtube.com/watch?v=7yKZLU1dPOk&ab_channel=JJP%26ELLC

Alternatively, the method below is appropriate:

1. Use either grease or low-strength thread locker on the threaded insert.

2. Use Park Tool SPA-2 or equivalent 2.3mm pin spanner to tighten threaded insert into fork. Flange goes on the OUTSIDE (see third picture).

3. Use grease on O-ring of thru hole insert and install into fork with a combined pushing and twisting motion. Do NOT use thru axle to drive the insert into the fork.

4. Use grease on threads of Thru Axle.
