What we like

The frame is a super stiff construction made of CrMo 4130 (Chrome Molybdenum), called Chromoly, that is much stronger than the most commonly used Hi-Ten. It gives the rider a very responsive feel enabling greater control.
We have paid the utmost attention to the SHAPE. Here we have implemented all details that we applied in the development of the Mad4One Alu-frame.

IRON MAD is a super stiff CrMo construction giving the rider a very responsive feel enabling greater control.
•    The most critical point in the unicycle frames is the junction between the seat tube and the crown.
•    The frame has a "one-piece" rein- enforced seat-tube that gives extra rigidity and strength.
•    The flat crown is excellent for foot placement during one-foot and stand-up tricks. It is also wide enough to limit the painful sensations you may have, and has two drilled holes machined from solid, that offer great anti-slip sealing.
•    Thanks to the rounded edges of the crown, the foot, that controls the wheel and manages the gesture, can move freely and without restriction.


IRON MAD is available in a range of standard frame lengths, but we can also custom cut a frame to the size of your choosing.  If you require a specific length frame, please just ask and we will be happy to sort you out with your very own custom fit frame.
