Description
1″ Threaded to 1-1/8″ Threadless Steerer Adapter – 195mm – Black
Notes from MyBikeThing This high-quality steerer adapter allows you to use modern 1-1/8″ threadless stems on vintage 1″ threaded forks. Featuring 60mm of height adjustment and robust construction, it’s perfect for modernizing classic frames. What sets this apart is its unique quill-style expander system that ensures rock-solid stability.
Condition Clean and straight with normal installation marks. Threads and expansion mechanism work smoothly. I’ve personally inspected the wedge bolt and expansion surfaces – everything moves freely with no binding. Got questions about compatibility with your vintage frame? I’m Paul – let’s chat about your build plans and make sure this is the right solution.
Workshop Wisdom Always grease the quill portion and wedge bolt before installation, but keep the threadless portion clean and dry for proper stem grip. For maximum stability, leave at least 35mm of quill inserted past the minimum insertion line.
