What is the typical speed of a road car? Comprehensive analysis of speed selection and hot trends
In recent years, the popularity of road cycling has continued to rise, especially the selection of transmission systems has become the focus of attention among riders. This article will combine the hot topic data of the entire network in the past 10 days to provide a detailed analysis of common configurations, applicable scenarios and the latest trends of highway speed classes to help you make a more informed choice.
1. Basic concepts of highway speed classification
The "speed" of a road car refers to the total number of gears provided by the crankset and flywheel combination. The calculation formula is:Number of front chainrings × number of rear sprockets. For example, a 2×11 speed system provides 22 transmission gears (the actual available gears will be slightly less due to repeated combinations).
| Speed type | Chainset configuration | Number of flywheels | Overall gear |
|---|---|---|---|
| 16 speed | 2×8 | 8 | 16 |
| 18 speed | 2×9 | 9 | 18 |
| 20 speed | 2×10 | 10 | 20 |
| 22 speed | 2×11 | 11 | 22 |
| 24 speed | 2×12 | 12 | 24 |
2. Popular trends in 2023
According to recent data from cycling forums and e-commerce platforms, mainstream road speeds show the following distribution:
| farewell | Market share | price range | Representative models |
|---|---|---|---|
| 2×11 speed | 42% | 5,000-15,000 yuan | Giant TCR, Specialized Tarmac |
| 2×12 speed | 28% | 8,000-30,000 yuan | Shimano Dura-Ace, SRAM Red |
| 2×10 speed | 18% | 3000-8000 yuan | Entry-level carbon fiber car |
| 1×12 speed | 12% | 6000-20000 yuan | Gravel Bike model |
3. Applicable scenarios for different speeds
1.2×11 speed system: An all-round choice, taking into account both flat road sprinting and hill climbing needs, suitable for most road riding scenarios, and the maintenance cost is relatively low.
2.2×12 speed system: The first choice for professional competitions, providing more delicate gear ratio changes, but requiring a higher budget and strict maintenance requirements.
3.1×12 speed system: A popular configuration for emerging gravel road bikes (Gravel), which simplifies operation and adapts to complex road conditions, but its top speed performance is slightly inferior.
4. Suggestions on purchasing
1.Beginner riders: It is recommended to choose 2×10 or 2×11 speed system, which is cost-effective and easy to maintain.
2.Advanced training: 2×11 speed is the best choice to balance performance and price, with many options for replacement accessories.
3.competitive needs: A 2×12-speed top-end kit can be considered, but it needs to be paired with a high-frame wheelset to maximize the benefits.
4.Complex road conditions: The 1×12-speed system is more suitable for mixed terrain riding and reduces the risk of front derailleur failure.
5. Maintenance tips
• High-speed systems (11/12 speed) require the use of special chains, ordinary chains may cause tooth skipping
• Clean the flywheel and guide wheel regularly to prevent sediment from accelerating wear and tear
• It is recommended to replace the transmission cable every year to maintain shifting accuracy.
• Pay attention to the battery life of the electronic transmission system, and carry a spare battery when riding long distances
Conclusion:The choice of road speed class requires comprehensive consideration of budget, riding scenarios and maintenance costs. The current market mainstream has transitioned from 2×10 speed to 2×11/12 speed, while 1× system is emerging in specific fields. It is recommended that riders choose according to actual needs and do not blindly pursue the highest speed.
