Designed and developed by Mad4One for FREESTYLE.

Light, however stiff and strong, the BEST CHOICE for a LONG-LASTING FRAME.

Seatpost 27.2 and vertical tube 31.8 make this frame much more steady than the ones with smaller diameters. 

The most critical point of the unicycle frames is the junction between the seat tube and the crown. The MAD frame has a triple butted reinforcement seat-tube that makes it one of the strongest. 

The MAD frame offers a larger flat crown. Standup and coasting tricks become much easier. Thanks to this wider surface you can perfectly control your freestyle. Perfect round edges of the frame make your foot gesture really smooth and fluid. 

The crown has two "false holes" made of solid,  which offer a rock-solid-grip underfoot pressure. 

We know that for stand-up there is not a "standard" distance between crown and tire that can be considered the BEST by all freestylers. This is strongly linked to the style of each rider. However, we are convinced that the shape of the new MAD frame will be well appreciated by almost all freestylers. 

We have noticed that some Producers insert in their frames a very long seatpost in order to increase the robustness and stiffness of the frame. This is not necessary for our frames. It is sufficient to have a length of 10-15 cm to ensure the best stiffness. All seatpost in excess is just unnecessary weight.
