Summerville N7 CB components
Fork material
The fork is made out of steel, which is tougher than carbon in the case of an impact. However, it can add some extra weight to the bike.
Wheels size
The wheels on Summerville N7 CB are the 700c aluminum type. These are the most popular wheels for road, aero, gravel, cyclocross, race, and gravel bikes. However, these wheels don’t perform so well when passing over obstacles.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The Summerville N7 CB comes with Coaster brakes. These brakes are pretty efficient, and they’re not so pricey. However, if your chain falls off or snaps, your coaster brakes won’t function anymore.
