ahead stem adapter for quill stems

In order to use the Twist Stem or other Ahead stems in combination with threaded forks, you can simply replace your classic quill stem with the by.Schulz Ahead Stem adapter for quill stems. The robust aluminium handlebar tube virtually represents a threadless steerer tube extension where you can mount compatible components on.

Thanks to high stability, the adapter can be mounted on hybrids, city bikes or e-bikes and is even adjustable in height without spacers.
