The Growler proves that the secret order of hardtail trail shredders is alive and thriving. Sure, it’s got that classic hardtail profile. But 21st century touches across the platform reveal a future proofed, instant classic. 29x2.6 tires for ridiculous grip. An aggressive ride character for surprising levels of confidence while descending or ripping tough trails. A refreshingly simple (and tough) package for rowdy days at the trails. More satisfying than a tropical IPA growler fill on a hot day—and way, way faster. Cheers, eh.

Intended use: Trail

Rear travel: Hardtail
