Overview
Here you can find a video on how to measure your forearms for our armrests. For the Canyon armrest, this is a guideline; the desired width of the armrest is the most important factor.
For assembly instructions for the risers etc. please follow the links on our YouTube channel, some of the product designs in the videos may contain older versions.
For the BTAs, there are assembly instructions in video format or you can download the written version here as a PDF by clicking on the button:

This table is intended to help you select the correct size for the standard armrests.

For the Canyon armrest, the table can be used as a reference, but the distance from the outer edge is more important. This is the maximum width, i.e., how far apart you can place your arms.
