2.1 components
Fork material
The fork on this bike is made out of carbon, so, it’s a great addition to the bike’s value. However, carbon forks should be regularly inspected for damage because even the smallest crack could cause the fork to fall apart.
Wheels size
When leaving the production line, the 2.1 model has 700c aluminum wheels. These wheels are the most used kind for road bikes in general. 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 2.1 has Rim brakes. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, they have problems in wet conditions.
