There's a massive variety of performance across the spectrum we offer, from the first option we propose, good in what it does and comparable in quality to the disc brake systems you usually find on the best known mountain unicycles available on the market, to the more powerful ones, up to the 4-piston braking systems, which offers excellent modularity and superior stopping power in all conditions, instilling great downhill confidence and control.
The round Mad4One frames are made from aluminum alloy AL7005-T6, that compared to the more common AL6061-T6 has a greater load resistance (+ 12%) and a higher fatigue resistance (+56%). Furthermore, we paid great attention to the diameter-thickness ratio of the tubes and to all details such as the double disc-brake mounting tabs welded to the frame and the double hydraulic brake hose guides.
All aluminum cranks mounted on our mountain unicycles are 100% compatible with any ISIS-hub. They are the only cranks on the market made of AL7075-T6 aluminum alloy. The most important benefit of this alloy is its high resistance to stress and strain (AL-6061 does not have the same high strength). AL-7075-T6, tradename ERGAL (the best of all conventional aluminum alloys), is an alloy of aluminum and zinc, which is mainly used in aviation, especially in structural parts, and in competition, especially in car and motorcycle racing. From a mechanical point of view, ERGAL 7075-T6 is by far the strongest aluminum alloy.
