Couple of thoughts right off: 1. if you pull the stem out to the minimum insertion line and re-tighten it, does it still move? Sometimes, if you've inserted the stem too far, you may encounter this issue. It can be mitigated by getting a shorter stem or cutting the current one down a bit (advanced mode). 2. What's the inner diameter of the steerer and what's the outer diameter of the stem? There are different threaded headset standards. I've provided a summary below. It's possible you've wound up with a mistmatch:
*Stem “neck” outer diameter* – measurement units: mm (inches) *Standard name* *21.15 (13/16″)* Old American and BMX standard *22* Old French standard *22.2 (7/8″)* Standard for most threaded forks with an outer diameter of 25.4 mm (1″) *25.4 (1″)* Standard for most threaded forks with an outer diameter of 28.6 mm (1 1/8″) – not very common On Wed, Sep 6, 2023 at 3:07 PM Richard Rose <rmros...@gmail.com> wrote: > Greetings folks.
