Cycling Experience

The Rocky Mountain Growler 50 is a well balanced bike in all aspects of riding ability. For me, it’s a bike that I can’t go wrong with and allows me to have all my needs somewhat met.

To that end I planned to ride through Wayne National Forest (Ohio) using the Rocky Mountain Growler 50. I booked a neighboring hotels on IHG, packed my bike and headed out.

The route is a mix of steep climbs and loose dirt forest trails and intense, bumpy, fast descents.

Climb Uphill

The Rocky Mountain Growler 50’s climbing ability was very strong, and the excellent state of the geometry and the hardtail frame construction made my climbs more efficient.

The power transfer of pedaling was dry and crisp, without the feeling of letdown and heaviness in pedaling that is associated with the full-suspension type of mountain bikes.

Then when the gradient got steep, the richness of the 1×12 speeds and the 30T discs gave me endless confidence to climb over any angle of incline. It brought me endless confidence to climb over any angle of uphill.

Finally, the excellent geometry kept my center of gravity stable.

My weight could be distributed on both ends of the bike, and the Maxxis Minion DHF’s 2.6-inch, large-grain outer tires kept the bike dead center on the ground, ensuring that I didn’t experience any slippage in my pedaling.

Riding upwards was also much more efficient, allowing me to maintain a good climbing riding rhythm and keep riding faster.

Go Down

The Rocky Mountain Growler 50’s performance on the descents is what I like best about it.

The slack geometry and longer bodywork made for a smoother, faster ride on these rough and intense high-speed descents.

Besides, the RockShox 35 Gold RL shock fork with 150mm of damping travel absorbed all the jittery road shocks, keeping the bike’s body stable and not overly bumpy.

However, with the hardtail construction, the bike’s rear wheel could still be too jumpy during intense riding, which requires a certain amount of bike control skills.

Then once on the trails, the Maxxis Minion DHF’s 2.6-inch large-grain outer tires gripped well enough to keep from slipping even on loose dirt surfaces.

The shorter fork reach has a nimble handling that ensured a quick enough descent on the trails.

Finally, the hydraulic brakes of the Shimano MT4120 were coupled with the front and rear 180mm discs, and the braking ability was also strong and reliable enough to reduce the speed of the bike in a very short period of time, ensuring the safety of the ride.

All in all, the Rocky Mountain Growler 50 is a hardtail enduro bike that brought a lot of fun to ride and kept me entertained.


The Rocky Mountain Growler 50 is available in a total of (S-XL) 4 sizes of internally cabling lightweight aluminum frames for a cleaner, neater look and easier daily cleaning.

The 4 sizes of frames are suitable for riders from 5’2″-6’6″ in height to meet almost any rider’s choice.

Great geometry, coupled with a 29×2.6-inch wheelset, gives the bike great drop balance and passing power, while a shorter rear dropout ensures handling agility for trail riding.

The design of the dropper allows the rider to adjust their center of gravity at any time between climbs and descents for more stability, keeping the ride continuous.


Other Version

The Rocky Mountain Growler 50 is an excellent hardtail enduro bike with a strong and durable frame section and excellent geometry that ensures a strong performance.

For this reason we offer a hardtail enduro bike with the exact same lightweight aluminum frame, but using base components to make it a more affordable option for everyone.

Rocky Mountain Growler 20

The Rocky Mountain Growler 20 features the exact same internally cabling lightweight aluminum frame, a strong, geometrically excellent frame that gives this bike a trustworthy, reliable performance.

First of all, the Suntour XCM34 damping fork used has 130mm of damping travel. It can be adapted to riding on almost all complex surfaces.

In terms of drivetrain components, it uses MicroShift Advent X 10spd drivetrain, which is a reliable drivetrain, and with 1×10 speeds, it’s good enough for daily riding.

Finally, on the braking components, the Shimano MT4100’s hydraulic disc brakes, coupled with 180mm discs front and rear, are powerful enough to be trusted.

So if you’re on a limited budget, then the Rocky Mountain Growler 20 would be a much better fit with excellent frame carrying some potential for later modification and upgrades.
