Product Overview
The NITTO quill to threadless stem adapter, AKA Column Adapter is an adapter for using a threadless stem (most common stem size 1-1/8) with a threaded steerer.
If you are going to use a shim, adaptor, spacer or any other device and its location is critical to safety, it should be high quality and strong.
Nitto understands that testing and manufacturing a product so it's safe is important - This adapter is MTB rated and tough as old boots.
The NITTO-MTC comes in a few different versions so if your'er unsure, please get in touch.
