The core of the bike is one of the most important components of the transmission. It will be the part that allows the rear wheel to move when we pedal, and it is also the part responsible for the rear wheel to rotate freely when not pedaling.
The nucleus is also called a free wheel body. It belongs to the rear hub and the cassette is installed on it. It has specific teeth where the different cassette crowns will be inserted.
