Fork material

Wheels
When it comes to wheels, the Sirrus Pro bike is equipped with the 700c aluminum model. 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
Nothing is more important on a bike than its ability to brake properly. Specialized Sirrus Pro is equipped with Rim brakes. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, you could spend a little extra and get a bike that has hydraulic brakes.
