Overview of components
Fork material
The fork is made out of aluminum, so there won’t be much extra weight added to the bike. However, they are not so stiff as carbon forks are.
Wheels size
The wheels on Roll 7 are the 700c aluminum type. 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
We ride faster and faster, so a good braking system is essential on a bike nowadays. The Roll 7 comes with Rim brakes. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, they are not nearly as effective as hydraulic brakes are.
Sizes
This bike is available in 4 sizes. They vary from 158 cm – 199 cm (5.18 ft – 6.53 ft). In conclusion, you won’t have a problem finding one that suits you.
