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.

Deadly Trail Bike

I bought my Growler April of last year, I upgrade my tires to minions and my forks to Rockshox recons and this bike shreds on the trail. For a trail hardtail it’s deadly handles jumps great same for tech and climbs and descents amazing. Only reason I don’t give this bike a 5 is because the frames paint chips easy and I’m not to fussy on that. Other than that worth getting. If you plan on shredding this bike it is worth going for the growler 50 but if you are planing on doing casual trail stuff the 20 will do fine. I used to do casual stuff around when I got this bike but I quickly got better with more confidence and upgraded it to make it good for shredding and more confident.

Good bike!

This is a good platform to upgrade from, or if you are slow(like me) you can ride it as is. The XCM34 coil is very rigid and performs surprisingly well for have no dampening system at all, and is sprung pretty much perfectly for me at 190lbs, and has good bottom out resistance. I lubed it with slickoleum which helps its small bump smoothness.

The brakes, dropper, and 1x10 drivetrain work well enough, the tires aren't great for grip, but roll fast. I'm going to upgrade the tires first to tubeless and then see how I feel about the fork.

Absolute beast!

This may be the best aggressive hardtail on the market, especially for the price. This bike slays the descents! It is super stable and begs to go fast! It climbs perfectly fine. It is fairly light weight (mine is sitting around 30lb). This is a bike that can ride almost any trail and can stay in your fleet forever. If you buy the 20 and add on your own upgraded fork and tires, then you can have a epic ride and save a lot of money. If you plan to upgrade, then it is not worth buying the Growler 50.

Some things lacking...

I bought this bike mostly for the frame, because of the angles, threaded BB and water bottle mounts. I'd give the frame 5 stars but the paint job is very prone to chipping, and the chain stay protector was already peeling off upon delivery :( Equipment wise, the fork is a boat anchor; this is the heaviest bike I own by far, including my other hardtails. I swapped it out pretty quick. The square taper BB is a necessity at this price, but OK. I love the gearing. My main beef is with the tire choice and that the rims came out of true within 5 rides and the spokes were loose. That just shouldn't happen. I'm used to Rocky using Wheeltech wheels that stay true until you taco them, and even my last girlfriend stayed true longer than these rims. The Kenda tires? C'mon Rocky, you can do better than that. They aren't even tubeless ready. Bike rides great and the straight seat tube allows for a 210mm one up dropper on the size L. If you are taller, you could probably fit a 240 on the size L.
