Cyclist type: beginner. Development options: 2x8, 3x8

Shimano Sora

The Shimano Sora group is another group for low -end bicycle assemblies. In this case it is somewhat more sophisticated than the Claris and is intended for more sporty use, especially for the introduction of the 9 -speed cassette. It includes the entire transmission group, in addition to brakes and bushings for the wheels. Its construction is more robust and resistant than Shimano Claris. In addition, the current series, the R3000, inherits and adapts some of the designs and technologies of higher groups, such as the design of anti anti -chain departures HG.

Shimano 105

Shimano 105 diversion The passage to the mid -range of Shimano begins with 105, the group of cyclists par excellence. Also of cyclists who usually go to train and who do not want to spend much on a high -end bicycle or components. The Shimano 105 change is the group with the best quality/price ratio of the brand, reliable in change and inherits a good part of the design of connecting rods and ultegra dishes, the group immediately higher than it. The connecting rods of 105 (with 53-39d, 52-36d and 50-34d) But, at the same time, it has a special forged that increases its rigidity and thus improves the energy transfer of the pedals to the bike.

High -end shimano groups

Shimano reserves its electronic change system for high -end groups, for professional and semi -professional cyclists or fans seeking more demanding performance in their outputs and routes.

SHIMANO ULTEGRA DI2

Shimano Ultegra change handles The new R8000 generation of the Ultegra Group includes a renewed DI2 electronic change version, whose technology is directly inherited from the Dura-Ace2, cusp of the offer of Shimano transmission groups. The Shimano Ultegra Di2 group combines that electronic change technology with the components of the ultegra, with dishes, connecting rods and cassettes somewhat heavier than the Dura-Ace. However, the reliability and customization capacity of electronic change is practically the same as the top of Shimano range. It is thanks to the button with programmable button. In addition to the change, with it you can also control a system of lights, link it to a GPS to handle it better or program the exchange rate (fast or synchronized) that most adapts to the cyclist's driving style. All this can be configured from the application Shimano e-Tube, available for both PCs and mobile devices (tablets and smartphones). Shimano's electronic change brings numerous advantages to the cyclist. First, both buttons and deviators (striker and rear) are much less disagree, thanks to their connection by electronic cable, which is able to operate the small engines of the deviators to change the dish or pinion. The entire system is fed by a battery that can be installed inside the box, usually inside the armchair tube. It is also possible to customize the mode of change: of one manual, with the same sensations of change as a traditional one than with greater action precision, to one synchronized or Syncro-Shift. The latter acts as an automatic change; If you go up the front diversion will automatically change to the small dish and if you lower it will change to the big one, without pressing the handle of this front deviator. On the other hand, there is a Semi Syncro-Shift mode. Only by changing the dish the system automatically operates the rear diverter to raise or lower three pine nuts and adapt the relationship instantly. Then, the cyclist himself can upload or lower a pinion manually to completely adjust the development. You can see how the different modes are adjusted in this practical video of Macario Llorente: https://youtu.be/e0M8HAtaosI But all novel technology is rigged from some inconveniences. In the case of the Ultegra Di2 change there is weight gain regarding a mechanical change. In addition, in case of system fault (rare) repairs are more expensive. Cyclist type: High level cycling, corridor. Development options: 2x11. Rivals on the market: SRAM FORCE ETAP AX.

Shimano Dura-Ace
