• Initially headset has a lot of play and handlebars turn freely
  • Tighten it a little and handlebars bind somewhat, but headset still has a lot of play
  • Tighten it a bit more just so almost all play goes away, but handlebars feel very stiff – they do not turn easily

The frame is custom built, but I’ve never experienced anything like this on any of my other threaded headset bikes with cheaper headsets.

Headset is a Tange Levin NJS 1” (26.4mm)
* 1" threaded
* crown race: 26.4mm ISO or 27.0mm JIS
* ISO has a 30.2mm cup diameter; JIS is 30.0mm
* NJS certified

What’s wrong with this headset?

  1. the cups are loose in the headtube, possible. or some parts of the headset got switched up in installation. caged bearings are upside-down. wrong number of loose ball bearings (if you’re in doubt, fill up the entire race, then remove one). just some thoughts!
