Overview of components
Fork
The Stormy 20 comes factory-installed with the SunTour fork. This has a travel range of 40mm. Bike forks are great for shock absorption and provide you with a smooth ride. In short, you should always ensure you have a good fork when purchasing a bike.
Fork material
The fork on this bike is made out of aluminum, which is a lighter material. However, it is not as tough, nor durable as steel is.
Wheels size
The Stormy 20 2015 bike is equipped with 20″ wheels when leaving the factory. The 20″ wheels are a good fit for folding bikes, BMX, or children bikes. In conclusion, you can use them better on-road, and less on technical terrain.
Brakes
For your safety, it is important to have quality breaks on your bike. K2 Stormy 20 has Rim brakes installed. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, they have problems in wet conditions.
