The Slackline is a multipurpose Allmountain Hardcore hardtail frame with a strong 4X/Slalom influence to its design. It is designed to reward style while riding hard in all conditions. The double butted reynolds 631 tubing used to make the Slackline was chosen for its manipulative properties and excellent vibration damping.

Directional flex control is key in the Slackline's design as the frame uses carefully selected tubing to offer a direct and controlled ride combined with mega strenth.

The snap, acceleration and berm hugging cornering comes from our low bottom bracket and short chain stays. Couple this with a tight, nimble geometry and slack angles; you have a versatile “bomb proof frame”.
