A rigid and light handlebar, good ergonomic
Deda Presa RHM is a crease in carbon outlet airfoil. Available in two versions, natural or white carbon, has a new ergonomic RHM, Rapid Handle Movement, which allows an easier and faster moving of hands at the various positions of the curve.
With a new definition of the values of reach and drop (depth and height of the curve) and a different design of the radius of the curve, we obtained a more comfortable and exceeded the limits of traditional anatomical folds, where you can one hand position. Now with a continuous incremental radius for the hand to the fold challenge from several points, giving the best comfort and the right angle of the elbow and the correct and natural support of the palm of your hand. The new reach is 75 mm, against the usual 86 millimeters, while the drop is 127 millimeters, values much lower than before, with less distance between high and low grip. Present the internal cable. The sizes available are 42, 44 and 46 (values outside-outside). The declared weight is about 209 grams, in size 42 of we have detected 225g.
Road test
Deda Presa, which completes the range so far tested (ZeroNero and SuperZero) is achieved impeccable. Perfect paint and easy assembly. Driving appreciates the proper size of the airfoil, not particularly strong and able to accommodate medium-small hands, allowing always a firm grip and secure. The new conformation of the radius of the fold and the values of height and depth of it, in fact lead to a better transition between the different handles possible, but above all a more reliable and comfortable grip. With low hands on the handle levers are at your fingertips and control always secure the reduced depth and height can stay with the body slightly more than usual, reducing the cervical lordosis and the load transfer on the wrists. This equates to a better comfort over long distances, but who prefers a "stretched" position must include an attack longer than about 1 centimeter to find the "old" position. Even with his hands on the handle high, close to the controls, the comfort is excellent. The rigidity of the fold is a test of speed and powerful united stem ZeroNero, is a set sure to satisfy both users more powerful and demanding. Excellent also the ability to filter hits the ground and ensuring optimal comfort. Compared to the handlebar integrated Alanera RHM, you gain weight while the stiffness remains integrated for the benefit of the fold as well as comfort. To report that to maximize the most light weight and rigidity to the jack should be combined attack Zero 100 Servizio Corse, renouncing a bit of comfort, but even more by reducing the weight of the drive, increasing its rigidity. With the handlebar Presa we tested also Deda tape provided a multitude of colours, perforated or not, has proved a reliable product quality and resistance, ensures a sure grip, absorbs sweat well and cleans easily; beautiful caps in carbon look and colours, such as Green Apple and Red.

Handlebar Presa costs 239 Euro in the natural carbon version, and 255 Euro White version, but high prices are justified by a quality almost perfect. Handlebar tape is priced at about 8 Euros, a competitive price.
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.

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
A very light and stiff seatpost, great care constructive
At the top of the Deda Elementi range we have the SuperZero seatpost, which goes to the crease stem ZeroNero and handlebar Presa.
All three components are characterized by the quest for low weight and made of carbon. The seatpost SuperZero is available in two different diameters, 27.2 and 31.6 mm, with a single length of 335 millimeters. The setback of the saddle is about 22 millimeters, while there are two screws for fine adjustment of tilt of the saddle. It's available in white or natural carbon. Is declared for a weight of 166 grams, in 31.6 mm diameter we found a weight of 199 grams.
Road test
The SuperZero seatpost is very fine, excellent care to its construction, also in white, which unfortunately leaves only partly see the beautiful texture of carbon with which it is made. Beautiful and well made of light alloy components. The adjustment of the seat is excellent and the twin screw which is attached to the sled allows for very accurate adjustment of tilt of the saddle itself. As always it is good to observe the tightening torques of the screws to avoid irreparably damaging the carbon fiber parts. The actual weight, though distant from that stated (but the model refers to the diameter of less then quite realistic) is very competitive and confirmed what we said in the past: it is often preferable an excellent seat post like this, very light, instead the solution of integrated seat post, then when you use micro seat post very heavy, well over SuperZero, which in fact annul the theoretical weight savings. In the saddle you appreciate the high rigidity of SuperZero, which bends the least and does not emit any noise, even minimal. Its high stiffness can also be seen on the uneven, where filter less vibration than other models in carbon, but remains on a level of comfort that most excellent and far superior to aluminum seatpost. In conclusion a great seat post, very rigid and light, perfectly finished. Excellent bike for a high level, rigid and lightweight.
