Condition: Excellent used condition. No damage, threads clean, expander plug intact. Ready to install.
Notes from MyBikeThing: The correct OEM hardware for a Reynolds Ouzo 1″ threadless fork — these get lost or damaged during builds and are a pain to source. If you’re restoring an Ouzo (or any 1″ carbon steerer tube), this is the piece you need.
Workshop Wisdom: The top cap bolt on a threadless system sets bearing preload — it is not a structural fastener. Snug only (3–5 Nm), then lock down the stem clamp bolts. Over-tightening the top cap crushes the headset bearings.
Guarantee: You put in the miles, we put in the work! 30 day Guarantee, rest assured of fit, function and condition. 🙂
