A carbon stem not very light, but very fine and hard

After analyzing the seatpost SuperZero, it is now ZeroNero stem, which is the ideal continuation of the range. The new stem is composed of a carbon fiber body and a number of parts in light alloy. The latter, in addition to the screws, are the two rings that allow the attachment to the fork, the two rings and the bezel that close the handlebar. So it is better utilized the mechanical properties of two different materials. Even in this case, the stem is available in natural colour or black carbon. The length can be 90-100-110-120-130 mm. The declared weight is approximately 145 grams, the same we found the extent of 100 mm. The height of the sleeve is 55 mm while the pair of tightening of the screws is 8Nm.
Road test
The ZeroNero, continues the concept of high quality and unique products that distinguishes all Deda products of the highest range. Has not fully implemented a particularly low weight, especially if you compare it with the Deda Zero 100 Servizio Corse unfortunately it seems that the carbon fiber in this case can not get that advantage in terms of weight it has in other products. In part, however, is a clear desire to create a very solid product and exclusive, like the exquisite realization of small alloy parts suggests. The mounting is simple, just respect the tightening torques of the screws. In the saddle you appreciate the high rigidity of this attack, quite comparable to the model Zero 100 Servizio Corse, who in the field can be considered an absolute point of reference. The real difference between the two models is in behaviour their on uneven, while the Zero 100 is always very stiff and "dry" in its responses, the ZeroNero filters and absorb the bumps and vibrations that come from the ground, making driving less stressful, more comfortable and fluid. Never fails stiffness, but there is more that comfort that other models, so rigid they can not boast. Obviously nothing striking, but definitely noticeable. Therefore the slight increase in weight can be easily justified and becomes acceptable if you try a certain comfort in addition to the absolute rigidity. Compared to other models, full carbon, however, is delighted by the choice of Deda not stake everything on weight, but privileged and point the rigidity of the component, which in fact is excellent and superior to other models, always full carbon, jumping into the limelight with weights well over the content of this ZeroNero. A stem, therefore, that a bike is to high range, high performance, but do not want to have comfort. The high price may be the only real obstacle to its spread; 190 Euro for the Carbon version and 209 for the White version, there are few, but justified by the performance and build quality, which remains higher than many similarly priced competitors . Online, you can also find a significant discount, around 150 Euro.
