The Heller Shagamaw is a 27.5+ carbon hardtail mountain bike frame that is primed to attack the trails. The sculpted carbon frame delivers stability and stiffness, with a modern, ready-for-anything geometry that encourages you to continually hunt out new gnar. The frame features a Boost 148mm rear axle and is optimized for a 1x drivetrain. Internal routing for cables, brake lines, and a dropper post keep the aesthetic clean. Designed around a 130mm-travel fork, the headtube is slack so you can attack the descents. Grab a Shagamaw and get to it!
