2023 Rocky Mountain Growler 40

The 2023 Rocky Mountain Growler 40 is built for riders who want a bike that handles everything the trail can throw at it, without getting bogged down. It's tough enough to take on rough terrain, but nimble enough to stay lively under your control. You’ll find a solid aluminum frame at its heart, one that balances strength with a manageable weight. When the trail turns tricky, a responsive bike makes all the difference.

Shifting gears feels smooth and natural thanks to the Shimano Deore drivetrain. It covers a wide range of terrain, from steep climbs to fast descents, so you can focus on riding instead of fiddling with the gears.

Up front, the Suntour Raidon 34 LOR Air Boost fork delivers 140mm of travel. That means bumps get soaked up, so your ride stays comfortable and controlled. You can dial in the air pressure just the way you like it, giving the suspension a plush yet responsive feel.

The wheels come tubeless-ready, wrapped in Maxxis Minion tires that carry serious grip. The WTB ST i30 rims are wide enough for larger tires, which aids stability and cornering performance. Running tubeless helps fend off flats and lowers rolling resistance, so you spend more time riding and less time fixing flats. Braking uses Shimano’s MT4100 2-piston calipers, which bring solid stopping power without feeling grabby. It's enough control to keep you confident on fast or technical sections.

At the rear, the 148mm steel Boost axle stiffens things up and adds space for those wider tires. This boost in rigidity means the back end stays stable when you're hammering through tough spots or throwing the bike around tight turns.

The Growler 40 sticks with you through everything: steep climbs, rocky flats, and rooty singletrack. It's practical without sacrificing fun and ready for riders who want a reliable partner out there on the trail.
