Headset harmony: 3D tech helps 80s hero.

One of my all time favourite components is a Shimano 600ex headset: beautifully over built, but with a finish that is as fragile as it is wonderful, and adorned with kooky non-standard star-shaped locking faces.



They need a special tool which is often more expensive than the headset (or old bike you just bought because of the headset). As a result many have been bodged with vice grips and other work arounds. Well here’s a cunning thing: 3D printed adapters that allow you to use a standard 36mm spanner. And they work. Available on the Bay (I have no affiliation - just sharing a useful thing.)

Interesting idea. not convinced of the torque loading of the plastic, but for low torque applications it should work just fine.
clever to allow a split too, so you can get them on and off.

Yes, you’re right: I’ve just been trying it out on a stubborn frame that hasn’t been touched in an age and it’s struggling. Useful for adjusting good sets so you don’t scratch the finish, rather than wrangling shitters.
