The MAD-Race

 

Mad4One, the unicycle for speed track

24" and 26" (both comply with the IUF Class 24"), aluminum frame, alloy AA-7075-T6
 

The 3 configurations: EVOLUTION ► RACE ISIS ► RACE TECNO

 

 

Contrary to the bicycle, the unicycle has only one point of contact with the ground, so when we push on the pedals, the force we apply on them makes the wheel spin around the hub, but at the same time it also pushes sideways towards the point where the unicycle contacts the ground. This produces the classic side-to-side oscillations of the unicycle, which is the number one enemy of high speed. The oscillation generated by our pedaling can be reduced by reducing the distance of the pedals from the center. This is the reason why if we want to have a high performing race unicycle the distance between the pedals must be as much as possible narrow.

We have worked on the weight distribution, reduced as much as possible the distance between pedals thanks to our 85mm hub, we have optimized both cranks and interface connecting cranks- hub, we have achieved a high level of stiffness of both frame and wheel.


All MAD-RACE unicycles (24" and 26") comply with the IUF 24" Class


A few words about the 24 Unicycle Class according to the IUF Rulebook.

The IUF Rulebook (go to chapter 2B.2 of the “2019 Competitor Rules”) does not specify the size of the tire, it refers only to "the tire diameter range"  allowed, that is,  the diameter of the entire wheel including the tire.

As regards the 24" Class it says that the diameter range must be "more than 518mm - 618mm"  and the cranks must be at least 125mm long.

  • The MAD-RACE 24” has a wheel-diameter, including the tire, of 606mm.
  • The MAD-RACE 26” has a wheel-diameter, including the tire, of 616mm.

Therefore all MAD-RACEs comply with the IUF 24" Class.

There may be some variations due to the tire pressure.

 

Here's a short description of the 3 configurations we propose: the MAD-RACE Evolution, the MAD-RACE ISIS and the RACE-TECNO.

The HandleSaddle in SPEED TRACK

 

The HandleSaddle helps to keep your unicycle firm and stable in speed, especially in cornering.

The HandleSaddle is the new generation of saddle developed by Mad4One in ALU 6061-T6. 
In speed track we mount size M. The grip tape is available in 9 different colors, weight 783 gr. No doubt, the advantages are great, but you have to practice and get used to this new way of mastering your unicycle.
