Overview of components
Fork material
The fork is made out of steel, 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 Sirrus model has 700c aluminum wheels. There is no doubt, that 700c wheels are very popular on all road bike models. However, while they give you great speed and control, these wheels are not so bump-friendly.
Brakes
When you want to stop the bike in time, the brakes are vital. The Sirrus has Rim brakes. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, they have problems in wet conditions.
Sizes
This bike has one size only, so it might not fit you. In conclusion, make sure it fits you, or look for another model.
