The frame
has been designed with large diameter tubes that provide great stiffness and stability. The alloy used AL7005-T6 provides great durability and high resistance to load and fatigue. The most critical point of the unicycle frames (both shapes, square and round) is the junction between seat tube and crown. This MAD frame has a double butted reinforcement seat-tube that makes it one of the strongest.

The Disc Brake

According to the experience acquired in the last 4 years the most important feature in the braking system is not the power, but the braking modularity or the simplicity to use the brake. Other important characteristic is the resistance to the long-term use, that generates a lot of heat (pay attention, the disc becomes hot!). Based on these considerations we can say that nowadays the most suitable disc dimension is 180mm. However, according to all standards, the basic dimension is 160mm disc. Therefore you have to add an adapter for the 180mm disc. Our disc brake mount has been developed according to the standard IS2000Front. As adapter we advice the post mount/IS 180Front.
