When it comes to competitive cycling, the Tour de France is one of the most prestigious and challenging races in the world. From the grueling mountain stages to the flat sprints, the riders need to be in top physical condition and have a bike that can handle the demands of the course. One of the most important factors in a Tour de France bike is the number of gears it has. In this blog post, we will explore the history of gears in Tour de France bikes, the benefits and drawbacks of different gear ratios, and the current state of gear technology in the sport.
The History of Gears in Tour de France Bikes
The Tour de France has been around for over a century, and in that time, the technology of the bikes has evolved significantly. In the early years of the race, most riders used single-speed bikes with a fixed gear ratio. This meant that the riders had to pedal at the same speed regardless of the terrain, and they had to rely on their legs to provide all the power. As the race grew more competitive and the routes became more challenging, riders began to experiment with different gear ratios.
In the 1930s, riders started to use 3-speed hubs, which allowed them to switch between different gear ratios. This was a significant improvement, as it allowed riders to conserve energy on the flat stages and tackle steep hills with more power. In the 1950s, derailleur gears were introduced, which allowed for even more precise gear shifting and a wider range of gear ratios. By the 1970s, most riders were using 10-speed bikes, and by the 1980s, the Tour de France had transitioned to the use of 12-speed bikes.

Benefits and Drawbacks of Different Gear Ratios
The gear ratio of a bike refers to the relationship between the size of the front chainring and the rear cog. A higher gear ratio means that the chainring is larger than the cog, and a lower gear ratio means that the chainring is smaller than the cog. In general, a higher gear ratio is better for flat stages and sprints, as it allows the rider to pedal at a faster speed. A lower gear ratio is better for climbing and steep hills, as it allows the rider to apply more power to the pedals.
One of the main benefits of a higher gear ratio is that it allows the rider to go faster. This is especially important on flat stages and sprints, where the goal is to cover as much distance as possible in the shortest amount of time. However, a higher gear ratio also means that the rider has to pedal at a higher cadence, which can be tiring and can cause leg fatigue. Additionally, a higher gear ratio can make it more difficult to climb steep hills, as the rider has to apply more power to the pedals.
On the other hand, a lower gear ratio is better for climbing and steep hills, as it allows the rider to apply more power to the pedals. This is especially important on the mountain stages of the Tour de France, where the riders have to tackle steep gradients and long climbs. A lower gear ratio also allows the rider to maintain a more consistent cadence, which can help to conserve energy. However, a lower gear ratio can make it more difficult to go fast on the flat stages and sprints, as the rider has to pedal at a slower cadence.
Current State of Gear Technology in the Tour de France
Today, most riders in the Tour de France use bikes with 11 or 12 gears. These bikes use a combination of a small front chainring and a large rear cassette to provide a wide range of gear ratios. This allows the riders to switch between different gears depending on the terrain, and it gives them the flexibility to tackle both flat stages and steep hills with ease. Additionally, many Tour de France bikes now feature electronic shifting systems, which allow the rider to shift gears with the touch of a button. This can be especially beneficial on the mountain stages, where the riders need to be able to quickly shift into a lower gear when they encounter a steep gradient.
However, it’s important to note that having more gears does not necessarily mean that a rider will perform better. It’s also crucial that the rider is well trained and has the right gear ratio for the stage they’re competing in. Having a gear ratio that’s too high can result in wasted energy on flat stages and too low can result in not reaching the optimal speed on flat stages.
Tour de France Gears Explained
The number of gears on a Tour de France bike is a crucial factor that can make or break a rider’s performance. The history of gears in Tour de France bikes has evolved over the years, from single-speed fixed gear bikes to today’s advanced electronic shifting systems with 11 or 12 gears. Each gear ratio has its own benefits and drawbacks, and it’s important for riders to find the right gear ratio for the stage they’re competing in. With the right gear ratio and proper training, a rider can tackle the challenges of the Tour de France with confidence and success.
