Given the multitude of opportunities in terms of transmission, making the right choice is not always obvious. The latest developments in compact cranksets make it easier for cyclists. Here are some thoughts to help you!
There are a few years, practitioners cycling road bike saw appear triple transmissions trays, directly inspired mountain biking. The triple tray was the solution for any rider who wanted to climb the same mountain passes his idols Tour de France.
For some time, the reverse is true. More and more cyclists return to the double trays, and through compact cranksets and transmissions 11 speed, opening up new possibilities for staging and capacity.

A development opportunities
At the time, a good deal cassette pinion gear was a tedious exercise. Especially for cyclists moving in plain when mountain sessions ended up with reports impossible to take. It was then necessary to change the cassette to add a sprocket 26 or 28 teeth, which inevitably accentuated the gap between gears.
The chain was then all the evil in the world to stay in his place, and inevitably jumped when shifting gears. The result: a beautiful galley! This is where the “triple” bottom bracket came reshuffle the cards. With a combination of trays 50, 39 and 30 teeth, no more cervix was too high or steep.
With the arrival on the market, respectively 9,10 groups and 11-speed and compact cranksets, cyclists were offered a range of ever larger gears.
Another advantage is the compact lighter crankset, simplifies / facilitates transmission (under trays), optimizes the chain line by decreasing crossings and covers just about all developments used with a triple crankset.
A gear ratio suitable for … more constraints
When you live the plain, standard bottom bracket 53-39 teeth fully appropriate. However, for cyclists who move in hilly or mountainous buy tramadol area, the 39 teeth appear immediately much more difficult to take him uphill.
One solution is to change the cassette, the latest generation of derailleurs on the market in long cage, cassettes tolerate up to 32 teeth.
The most cyclists aware of this subject will tell you that this is not the best solution and that in configuring his road bike for the mountains, they sacrifice cadence. So too are major differences between the gears of the middle and the last gear. The aim is to expand the capacity of its transmission to the high percentages without giving up a high cadence.
The transmission 11 speed recently introduced to the market offered an excellent response to the high ratio cassettes by developing 11-speed, manufacturers have not simply proposed an additional report, but also a better staged transmission:
- the last 3 gears, the combination of teeth is essential to face the collar,
- and 8 other gears, which should be stepped convenanblement to roll in plain or on rougher terrain.
This is where lies the benefit of the 11-speed for practicing! Try tail lights for bicycle right on http://www.ebicyclelights.com/best/bicycle-tail-lights/.
In this sense the new 11-speed transmissions in compact (52×36, 50×34 or 50×36), offer a first real alternative to the traditional triple transmission , which until now was the only way to evolve in the mountains, when is not professional rider.
Whether with a pedal bike 10 speed triple, or a compact 11-speed, the rider has a great ability to mount the high percentages, but with the compact 11-speed, you get more of a better staged cassette, and you can blithely cross the channel compared to triple that tolerates little crosses.
