The cycling industry has developed hundreds of standards relative to all areas of the bicycle; bottom brackets, headsets, and in this case, thru-axles. During the early days of manufacturers specifically producing gravel bikes, circa 2015ish, the 15mm thru-axle was one of the early standards developed to replace the venerable 9mm quick release for disc brake bikes at the front wheel.

Continued from Above:

Some years later, 12mm was developed by a certain well known hub manufacturer, and quickly adopted as the standard for disc brake road bikes, and disc brake gravel bikes for the front axle. Consequently, the 15mm standard has all but been abandoned, rendering those bikes somewhat orphaned.
