Overview of components
Fork material
The fork on this bike is made out of aluminum, which doesn’t add too much extra weight to the bike. However, it is not so stiff as steel or carbon forks are.
Wheels size
When it comes to wheels, the 20 bike is equipped with the 700c aluminum model. These wheels are the most used kind for road bikes in general. However, these wheels don’t perform so well when passing over obstacles.
Brakes
Nothing is more important on a bike than its ability to brake properly. Principia 20 is equipped with Mechanical Disc brakes. They are much easier to maintain than hydraulic disk brakes. However, performance-wise there is room for improvement.
