Classic is back!

 

SONIC BOOM is a high-performance dirt jump frame. 

It is made of Aluminum that's rigid and responsive but lightweight, which is built for doing stunts, tricks, and go on rampaging.

It is designed with all the new up-to-date dirt jump features such as a tapered head tube and super-short chain stay & wheelbase lengths. 

The rear dropouts sit on a horizontal sliding system for easy chain tensioning and chain length adjustments.
