Sirrus Sport components
Fork material
When it comes to the fork, this bike has an aluminum one, so there won’t be much extra weight added to the bike. However, they are not so stiff as carbon forks are.
Wheels size
When leaving the production line, the Sirrus Sport 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. Specialized Sirrus Sport has Rim brakes installed. 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.
Sizes
Specialized Sirrus Sport 2011 is available in one size only. In conclusion, make sure it fits you, or look for another model.
