Hard trails on hardtail ain’t dead.

Meet the new standard in burly hardtail elegance.

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.

What sets the Growler apart

Holds the line

Hardtail isn’t dead—so we went all out in making the Growler as capable, aggressive, and as fast as possible on rowdy, rad trails. Charge hard—the Growler’s with ya.

Stubborn levels of traction

Sure, the Grower rips trails fast. But for technical climbs and loose trail, we opted for big rubber and “dig-the-hell-in” geometry to ensure ridiculous levels of traction and competence over the loose and uneven stuff. So good, it’s stubborn.

Monstrously fun

We purpose-built the Growler around 29 x 2.6 tires. The result is a fast-rolling, hugely competent, and impossibly fun hardtail machine. Fully internal cables and a boost rear hub really tie the room together on any trail, too.
