Cranks MAD4ONE - 6 Pin Narrow - Made in Italy - 125 Race ^*Required step

Since the beginning we designed and manufactured specialty components intended for high-level, competition unicycles. Since ever the focus lies heavily on research and refinement for all products to provide competitors with reliable and innovative TOP Material. Over the years, we developed 6 different types of hubs, 34 types of cranks, (including 5-Pin, 6-Pin short, 6-Pin long, 10-Pin ISIS compatible, and ISIS standard), all of which made from a special aluminum alloy that provides double resistance compared to the most commonly used alloys, we are speaking of the aluminum alloy ERGAL AL-7075-T6.

GENERAL INFORMATION

The cranks are mounted directly on the axle of the wheel (the hub) and in order to be mounted in a fixed and stable way both hub and cranks must have the same shape. This shape is the coupling interface. There are several different interfaces, each one defines the family to which the part belongs. Only hubs and cranks belonging to the same family can be mounted and used together. Standard families are the Square or Cotterless, and the ISIS interface, all the hubs and cranks belonging to a standard family can be used also mixing the products of different brands. There are also manufacturers who develop their own interface, that are called non-standard or proprietary. Hubs and cranks belonging to the non-standard families are not compatible with any others and must be used only with components made by the same manufacturer. In the past there were various non standard families. Almost all manufacturers had its own proprietary interface. Today the proprietary interfaces available on the market are the QuAx QX Q-Axle and the Mad4One 6-Pin and 6-Pin Short.

SOME IMPORTANT ASPECTS TO CONSIDER WHEN CHOOSING THE CRANKS

First of all the building methods. The cranks can be made from solid steel (the type of steel used determines the quality of the cranks), or from aluminum without steel compass for pedals, or aluminum with steel compass for pedals or from tubular steel. Another aspect to consider is the Q-factor. The Q-factor is basically the distance between the pedals. The higher the Q-factor, the better the lateral static balance. This plus is however not so important in unicycling,where the lateral balance is most of time a dynamic balance. The lower is the Q-factor, the more accurate and powerful will be your riding and you will move easier on one-foot, too. As in cycling, unicycling is always looking for maximum fluidity and the Q-Factor tends to be as low as possible. As for the cranks, they will have Q-Factor equal to zero if they are at 90° with respect to the hub. In this case a further improvement of the Q-Factor is possible only by using a narrower hub. In freestyle competitions often hubs of 90 mm or less are used instead of the standard 100 mm.

WHY DID WE CHOOSE AL-7075-T6 ALUMINUM ALLOY?

The Mad4One cranks are the only one on the market today made with ERGAL 7075-T6 aluminum alloy. Aluminium 7075, trade name Ergal (the best among all conventional aluminium alloys), is an aluminium and zinc alloy mainly used in the aeronautical field, especially in structural parts, and in the world of competition, especially cars and motorcycles. It is characterized by being by far the strongest aluminum alloy from the mechanical point of view.

The following MADapter are available:

MADAPTER Tecno: designed for the MAD-Tecno cranks.

MADAPTER made in Italy: designed for the Made in Italy cranks.

These two types of  MADAPTER are not compatible with each other.

On the AGILE cranks it is not possible to mount the MADAPTER.

The Cranks MAD-TECNO

2016 we introduce our line of forged standard ISIS cranks: the MAD-Tecno. They are available in the following versions: 1, 2 or 3 holes. They were made by forging to combine functionality-price-robustness.

Marco Vitale says: “These cranks born in my mind as training cranks, strong enough to resist any kind of “mistreatment” for long time, however not so expensive. The pedal thread is an important issue. We experienced, that nothing wrong happens to the thread, if you tighten your pedals in the proper way, but it is enough to ride once wit...h loose pedals, that you rip the thread. Now, after the first tests on the TECNO cranks I’ve learned, that Shape and Design are more important than the pure weight. Many testers have reported that the TECNOs’ weight is similar to the one of the old heavy cranks, but they work close to the lightest Mad4one, and their stiffness makes you feel more safe. Thank you to the MAD TEAM, that testing our products always helps us to improve!".

The AGILE cranks

The AGILE cranks are born in 2018 from the MAD-Tecno project, therefore they too are made with the ERGAL AL7075-T6 aluminum alloy (the strongest of the aluminum alloys on the market today), forged and optimized in the shape with CNC machinery to guarantee lightness (-30% compared to MAD-Tecno). We tried to reduce the Q-factor as much as possible and we succeeded. In fact, the AGILE are narrower than the standard ISIS, their Q-Factor (the distance between the pedals) has been reduced by 3mm per side, for a total of 6mm. THE PLUSES of the AGILE project?   ROBUSTNESS and LIGHTNESS.

The Cranks Made in Italy 6-Pin Short

The Mad4One unicycle for racing, the RACE EVOLUTION, developed in 2011 (5 gold medals at the World Championship 2012 in Bressanone - UNICON XVI), and further improved in 2018 (8 gold medals with Niklas Wojtek and Alina Czimek at the World Championship 2018 in South Korea - UNICON XIX), has a specifically designed interface. Why have we moved away in this case from the ISIS concept and therefore from a standard approach? To increase the effectiveness of the pedal thrust, we wanted to reduce the distance of the feet from the center, and to achieve this goal we designed a hub-crank interface that is less bulky than the ISIS.

The Made in Italy Cranks 6- and 10-Pin

Over the years we developed a valid and long term partnership with innovative CNC mechanical Centers in Italy, where the Mad4One Made in Italy cranks have been designed and produced. Thanks to this collaboration the product has been as much as possible optimized and we achieved a valid balance between weight and resistance. In 1010-2012 Mad4One brought to the market the 6- and 10-Pin Mad4One cranks. They are the right product for competition at high level, where the best efficiency and performance are required, in spite of the duration of the product (let's think of  the Formula1's Rally. Here some strategic components have a limited lifetime, however, their features are crucial to achieve the goal). The Mad4One 10-Pin cranks are 100% compatible with any ISIS-hub. The 6-Pin interface is a proprietary solution designed by Mad4One and is compatible only with 6-Pin parts produced by Mad4One, which are 6-Pin hub 100 mm, 6-Pin Disc hub 100 mm, 6Pin cranks.

What is the difference between Made in Italy 6-Pin and 10-Pin Cranks?

The 6-Pin differs from the 10-Pin in the diameter of the hub axle. The ISIS hubs have a diameter of 22 mm, the 6-Pin a diameter of 25 mm. Thanks to the larger diameter, we could make the 6-Pin with alluminum alloy ERGAL-7075-T6 and this gives them all necessary mechanical featurs to be the perfect cranks for Trial, Street, Flatland and Muni. Our tests have shown us that the ISIS hub made of the same material (the strongest aluminum alloy available on the market) can be used without problems in Freestyle and Race. However its behavior changes when the unicycle is under heavy stress: we have experienced that it is enough to make 10 hownhll jumps of 100 cm with 140 mm cranks and a rider weighting approx. 75 kg to break the hub. The 6-Pin system instead is usable without problems even in the most extreme Trial. A last consideration must be made about the concept of racing components: the aluminum used (ERGAL 7075-T6) has mechanical characteristics that allow the production of parts that are quite light and also robust. Aluminium, unlike steel, when subjected to stresses close to the maximum possible loads, has however a much lower resistance to fatigue. In fact, every time the load is closed to its maximum values, invisible micro-fractures are generated in the aluminum, and if these stresses last for a long period of time the component may suddenly break even if the load has never exceeded its the maximum possible load. Unfortunately, determining the length of the "fatigue" life of a component is not possible because it depends on many factors that are difficult to calculate and/or detect. Based on our experience we can say that even the lightest cranks we have designed have last a life more than sufficient to safely face some races and related training. Very important for the 6-Pin system is the assembly of the cranks that must be done correctly.

Here are some of the comments made by Top riders who first tried the MAD-Tecno cranks

Axel Kästle

"I ride the cranks now 2 weeks!The feeling from the old and the new cranks are the same! Maybe at grinds the new one are a little bit slifer!I´am 100% happy with the new cranks!".

Pierre Sturny

"Hi everybody! I'm proud to ride with the new Mad4one 125mm Tecno Cranks since two weeks now! I believe these are the best cranks ever. The design is really nice, with the mad4one logo like the old ones. The shape is really different from the old ones, and I'm sure they are unbreakable. The ISIS system is also different, with no Pins, it's easier to mount on your Isis axis. I use them for flatland and street now, with the new MADApter, on my opinion that's the best system for flatland combos. You can also have them on 135mm, perfect for Trial riding. The best news is the price, more or less half than the old ones. Enjoy your ride, with Tecno!  Pierre".

Patrick Schulte

"As one of the tester of the new Mad4one Cranks the techno cranks, I want to travel with you back in time where I started to learn all the flat tricks. 7 years ago I had cranks that were so dangerous to use. My foot smashing against the sharp edge, caused me to walk with pain for 2 weeks. Every other week I had to get myself a new pair of shoes, because they all got wrecked. What would life be if I had cranks like the techno Mad4one one's. The edge is softly and with the MadApter you have a big surface which makes rolls a lot easier, and safes the life of your shoes a lot ;) For flatland I would recommend you the 125mm version, but my personal favorite are the 114mm, yes size does matter ;) Of course with MadApter in your preferred color, individualize your Unicycle. In general if you are quite new to Street, Trial and Flat and looking for solid cranks go for the Tecno M41's!".

Adrien Delecroix

"Riding with them is very good, obviously I speak of flat and trial.... I do not see a lot of difference between the MAD-TECNO and the old Mad4One... they look very strong and also the shape looks strong.... the MAD-TECNO do not touch the frame any more, they are smaller...".

Oskar Ritter

"First of all, despite the new shape, I think the new Mad4One techno cranks feel almost exactly alike the normal Mad4one cranks. But the new shape makes them a lot stronger, without the weight being increased remarkably. Also the standard Isis system, without pins, makes it even easier to mount. So the cranks are stronger, perfectly shaped, only a little bit heavier than the previous model, and best of all, half the price of the original".

Eli Brill

"The new Mad4One Tecno cranks are rugged and sleek, and flip faster than any crank I've ever ridden. The zero Q design is also ideal for roll combos. I've been riding Mad cranks since the first prototype batch in 2010, and this new evolution is a welcome improvement to cranks that were already my favorite".

Welches Unterschied bigt es bei den verschiedenen Muni-Größen?

Wir beginnen mit dem Muni für die Kleinsten, das 20-Zoll Mini-Muni, das in der Konfiguration x2.60, x2.80 und x4.00 erhältlich ist. Klein aber mächtig mit allen Eigenschaften eines Muni für Erwachsene. Dann haben wir die zwei Zwischengrößen, das 24- und 26-Zoll. Leicht und einfach zu fahren, diese 2 Räder sind die richtige Wahl für Jungen und Mädchen, die an Körpergröße und Stärke noch wachsen müssen. Abschliessend kommen wir zu den Klassikern 27,5- Zoll, die die beste Wahl für Downhill (DH) sind, und die 29-Zoll perfekt für Cross-Country (XC).

Die Bremse beim Einrad wird anders verwendet als beim Fahrrad

Der wesentliche Zweck der Bremse am Fahrrad besteht darin, dass wir langsamer fahren oder anhalten können. Beim Einrad dient die Bremse dazu, die Geschwindigkeit zu regulieren und bessere Balance beim Bergabfahren auch bei hoher Geschwindigkeit zu halten. Dieser leichte und längere Gebrauch ist ein Fehler, der kostspielig sein kann.
