Sirrus Sport components
Fork material
Sirrus Sport has an aluminum fork, which is a lighter material. However, it is not as tough, nor durable as steel is.
Wheels size
The wheels on Sirrus Sport are the 700c aluminum type. 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
When you want to stop the bike in time, the brakes are vital. The Sirrus Sport has 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.
