How to use a handlebar stem extender

People who ride bicycles have a wide range of needs when it comes to the design and configuration of their bikes. One popular accessory for bicycle riders is a handlebar stem extender. A handlebar stem extender is a device that attaches to the stem of a bicycle’s handlebar and allows the user to adjust the reach, height, and angle of the handlebars.

In many ways, a handlebar stem extender can be seen as an essential item for bicycle riders of all types. Handlebar stem extenders are especially popular amongst cyclists who want to customize their bike’s handlebars to suit their individual riding styles. In this article, we will take a look at the different types of handlebar stem extenders, how they work, and how to use one properly.

Types of Handlebar Stem Extenders

To begin, let us take a look at the various types of handlebar stem extenders. The most common type of handlebar stem extender features a stem with clamps that fit different types of handlebars. The stem can be extended or reduced in length as desired, and the angle and tilt can be adjusted. Then, the clamps can be used to securely attach each end of the stem to the handlebars.

There are also varieties of handlebar stem extender that feature single clamps that attach to just one end of the stem. In this case, the stem will not necessarily be extended or reduced, but the clamps will be used to adjust the tilt and angle of the handlebars.

In addition, there are also varieties of handlebar stem extender that incorporate a more advanced design. Such extenders may feature two rails that are connected by a piece of pipe or tubing, and which can be adjusted in different ways to change the stem’s length, tilt, and angle.

Using a handlebar stem extender

Now that you understand the different types of stem extenders, let us take a look at how to use one properly. To begin, you will need to ensure that the handlebars are attached correctly and that the clamps are of the correct size and fit. To do this, you should begin by measuring the circumference of the handlebars (or estimate it if needed), as well as the diameter of the handlebars themselves.

The next step is to place the stem extender onto the handlebars and secure them using the clamps. In cases where the extender features two rails, the pipes or tubes will need to be positioned correctly and securely attached using nuts and bolts.

Once everything is in place, it is time to adjust the extender to the desired reach, height, and angle. This is done by turning the adjustment screw, which can be accessed at the back of the stem. When turning the screw, it is important to make adjustments in small increments to ensure that the stem remains secure and that the handlebars remain in their correct positions.

Finally, when the adjustment is complete, it is important to double-check that all the nuts and bolts are tightened securely before taking your bike out for a ride. The handlebar stem extender should move fluidly and without resistance; if there is any resistance or uncomfortable movement, it is important to make further adjustments to ensure the safe operation of your bike.


As you can see, there are a few different types of handlebar stem extender available, each of which requires a slightly different process for installation and adjustment. Regardless of the type of extender chosen, it is important to take the time to properly measure the handlebars, secure all clamps, and adjust the stem as necessary. When used correctly, a handlebar stem extender can be a great way to customize the reach, height, and angle of your bike’s handlebars; and make sure your bike is just right for your riding needs.
