Dimension Stem Raiser 1 1/8 Threadless-Black

Dimension Steerer extender (stem raiser) lets you raise your handlebars by 2 to 3 1/4 inches (50 to 80 mm)

This model fits 1 1/8" threadless fork steerers (the most common size for newer bikes.)

Once this accessory is installed, you can also raise, lower or even remove your stem without disturbing the adjustment of your headset.
