Push those pedals, hold the line, and enjoy what feels like infinite traction across rough terrain. The Growler is an incredibly capable hardtail that makes short work out of technical climbs, is ready to rail corners, and smooths out uneven ground. Like a fresh fill of a West Coast IPA, the Growler packs a punch of confidence with its 29x2.6" tires. Cheers, eh!

Plus-size rims and tires

Wider than standard yet narrower than fat, plus-size rims and tires hit the sweet spot in grip, stability, and speed, giving you more confidence on technical terrain. Compared to a standard tire you’ll feel grip in places you wouldn’t expect thanks to a bigger contact patch and greater rollover clearance. More air volume allows lower tire pressures which softens bumps and increases float on sand or snow. Whether you’re a novice or an expert, the benefits of plus-size tires and rims will amplify your mountain biking fun.
