We built the Extra ST inspired by our local trails where it’s right at home. It’s riding on these trails where behind every corner a root is your potential take off, a dip waits to be manualled or a rut becomes your next berm. The Extra ST is an enduro bike condensed into a smaller package which unleashes the most fun out of those trails.

Where a trail becomes too dull on a bigger bike, it becomes a playground full of opportunities on this bike. The shortened travel injects a healthy dose of playfulness and efficiency. There certainly is a danger of going too wild on this bike. But in those moments, the Enduro-worthy geometry will have your back and guide you out of trouble.

You are wondering what category of bike the Extra ST belongs to? We don’t know either. But be assured, it is more fun than any of them.
