Overview of components
Fork
The Growler 20 comes factory-installed with the SunTour XCM fork. This has a travel range of 130mm. Bike forks are good shock absorbers and provide a smooth ride and a great experience. In short, make sure you choose one with a decent fork when you purchase your dream bike.
Wheels
The Growler 20 2021 bike is equipped with 29″ aluminum wheels when leaving the factory. Having 29″ wheels means that you need less fork travel, leading to a reduction of the pedal bob effect. However, 29″ wheels will make your bike react slower to obstacles you may encounter.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The Growler 20 comes with Hydraulic Disc brakes. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, you can ride your bike with confidence.
Sizes
There are 4 sizes available for this model. Rider height can be anywhere between 158 cm – 199 cm (5.18 ft – 6.53 ft). In conclusion, you won’t have a problem finding one that suits you.
