Sirrus Expert components
Fork material
The fork is made out of carbon, so, it won’t add up to much weight to your bike. However, the price you have to pay for a carbon fork is considerably higher.
Wheels size
When leaving the production line, the Sirrus Expert 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 Expert has 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.
