Mad4One is worldwide Leader in the Design and Production of URBAN (Trial-Flat-Street) Unicycles and Spareparts.
Looking at the market: for the same price you get from Mad4One the BEST in Lightness, Stiffness and Ridigity.
The alloys used (ALU 7005 for the frame and ALU 7075 for the cranks) are of superior quality.
The hub i ISIS MAD4ONE made in Italy (the world's lightest hub in steel).
The four-cross spoke lacing system gives high stability and stiffness to the wheel.
The cranks MAD-TECNO ensure extremely high robustness.
The MAD-TECNO 19" Trial Machine is "ready to race" this means, the standard set-up (see for example the Tire we mount!) is the one used also by the best Riders of the MAD-Team and is the right one for your next Race, without adding or changing any part.
We have decided to mount the standard 42mm-bearings.  Why? We have understood that this is the RIGHT CHOISE for the BEST Reliability (= long lifetime of your unicycle) and the BEST Durability (= the ability of your unicycle to accept "hard work" for long time periods) of your uni.
