Black quill stem riser – RARE 21.1mm to fit older BMX, some early Raleigh MTBs, some Schwinn bikes
This allows you to raise the height of your quill stem by approx 10cm, for a more upright handlebar position
Simply remove old stem, install this riser then re-install your stem into the riser
Note that your bike may require longer cables to accommodate raised handlebar height!
