Slap berms, boost lips, and have one hell of a time aboard the Diamondback Release 4 Carbon mountain bike. Building off of the already well-established platform of the Release 29, this model boasts a new carbon fiber frame construction for a lighter and stiffer feel while maintaining the smooth and progressive nature of the Level Link suspension. Outfitted with performance oriented Fox suspension, the Release provides outstanding responsiveness that boasts small bump compliance while maintaining a bottomless feel for the hard hits that inevitably come with riding steep, technical terrain. Lastly, being fitted with a SRAM NX Eagle 1 x 12 speed drivetrain and G2 R brakes, the Release is ready to conquer (with complete and utter confidence) whatever obstacles the trails throw your way.
