Overview of components
Fork material
The fork is made out of aluminum, which is a lighter material. However, it is not as tough, nor durable as steel is.
Wheels
The Hotrock 20 Street Girls 2012 bike is equipped with 20″ aluminum wheels when leaving the factory. This wheel size is used on bike models like BMX, children, or folding 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. Specialized Hotrock 20 Street Girls has Rim brakes installed. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, you could spend a little extra and get a bike that has hydraulic brakes.
