Overview of components
Fork material
C9 Aluminum has a steel fork, which is tougher than carbon in the case of an impact. However, it can add some extra weight to the bike.
Wheels
When leaving the production line, the C9 Aluminum model has 700c aluminum wheels. These are the most popular wheels for road, aero, gravel, cyclocross, race, and gravel bikes. However, while they give you great speed and control, these wheels are not so bump-friendly.
Brakes
For your safety, it is important to have quality breaks on your bike. Public C9 Aluminum has Rim brakes installed. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, they are not nearly as effective as hydraulic brakes are.
