Fitness bikes average price

Sirrus components
Fork material
The fork 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
When it comes to wheels, the Sirrus 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. Specialized Sirrus is equipped with 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.
