P.20 Pro components
Fork material
The fork is made out of steel, so, it can add some extra weight to your bike. However, steel is a pretty tough and durable material.
Wheels size
When leaving the production line, the P.20 Pro model has 20″ aluminum wheels. 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
When you want to stop the bike in time, the brakes are vital. The P.20 Pro has Rim brakes. 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.
