When discussing bicycle drivetrains, one question often arises: should you choose a single, double, or triple chainring setup? This choice determines your ease of climbing, the speed at which you can maintain a good pace, and the comfort of shifting gears, whether you're commuting in Paris or exploring routes in the Île-de-France region. This article explains how chainrings work and the differences between their configurations to help you choose the option that best suits your riding style.

Platform: definition and operation
A chainring is a toothed wheel attached to the crankset, where the pedals are mounted. When the cyclist pedals, they turn the crankset; the chainring drives the chain, which in turn turns the rear wheels, propelling the bicycle forward. The number and size of the chainrings determine the gear ratio, that is, how easy or difficult it is to pedal depending on the situation: starting at traffic lights in Paris, long hills in the suburbs, or rides on the roads of the Île-de-France region.
Tray configurations
There are three essential configurations:
A single chainring or 1x
It's a very simple and popular system for mountain biking, gravel riding, and bikepacking. A single chainring is paired with a wide-range cassette, most often 11 or 12 speeds. This setup offers a sufficient gear range, simplifies use, and reduces the bike's weight, which is a real advantage for gravel rides, country outings, and daily commuting.
A double tray or 2x
A good compromise for those looking for a wider gear range than a 1x drivetrain. It's frequently found on touring bikes, road bikes, and XC mountain bikes, where speed on flat terrain and comfort on climbs are equally important. The double chainring is particularly popular for intercity riding and the hilly regions of France.
A triple tray or 3x
A classic setup, now found on older or entry-level bikes. The 3x offers the widest gear range, but it's heavier, not easy to adjust, and requires more attention when shifting. Triple chainrings are becoming increasingly rare, found only on some urban bikes used for short, leisurely rides.
Impact of chainring choice on pedaling
The single chainring setup embodies minimalism: simplicity, reliability, and reduced risk of breakdowns and mud buildup. It's an ideal system for mountain biking, gravel riding, bikepacking, and mixed terrain, very common in the Paris suburbs and rural areas. The absence of a front derailleur makes it intuitive to use: everything is controlled by the rear derailleur.
The double chainring offers an excellent balance between versatility and ease of use. This configuration is suitable for cyclists who alternate between roads, dirt tracks, and rough terrain. It also appeals to many road cyclists and those who combine urban commutes with more dynamic rides.
The triple chainring offers the widest gear range, but requires more attention to shifting and adjustments. It's a solution best suited to beginners on a budget who ride on very different routes and are looking for maximum versatility.
Criteria to consider
Bike type and riding style
The choice of chainrings depends primarily on the terrain you'll be riding on: Parisian cycle paths, suburban roads, parks, forest trails, or country roads. For mountain biking and gravel riding, often used on rough terrain, a 1x chainring is widely preferred. For touring and road bikes, popular for intercity travel, a 2x chainring remains a reliable choice. A 3x chainring can still be found on some inexpensive urban models.
Terrain and type of route
If you ride in hilly terrain, which is the case in most French regions, it's essential to easily find the right gear ratio. Here, the double chainring offers real pedaling comfort. For city riding and flat terrain, a 1x setup is more than sufficient.
Physical condition and experience
A wide range of gears is suitable for beginners and makes it easy to manage hills and starts in city traffic. With experience, many riders switch to simpler systems with fewer gear changes and less risk of error, especially for commuting and regular travel.
Reliability and maintenance
The fewer components there are, the more reliable the system. 1x drivetrains require little maintenance, making them particularly suitable for commuting, bikepacking, and long-distance rides. 2x and 3x systems add a front derailleur and additional adjustments, which require more attention.
Weight and ease of use
Fewer chainrings reduce the bike's weight and simplify pedaling. This is particularly noticeable on long distances and climbs.
Tips for choosing the right configuration
For city commutes, park rides or bikepacking in France, the single chainring is a simple and reliable solution.
For varied riding involving road, dirt tracks, climbs and long distances, the best choice is a double chainring, especially if speed and energy saving are important.
For maximum versatility at a low price, the triple chainring remains practical even with additional gear changes.
Conclusion
The number of chainrings is a key factor in cycling comfort. Before choosing your bike or upgrading your drivetrain, consider your most frequent journeys and your riding style: Paris, suburbs, or trail rides.
