Introduction
This article is intended for cyclists who are interested in learning more about single speed gravel bike gearing. It will provide an overview of the different types of gearing available, as well as the pros and cons of each type.
Single speed gravel bikes are becoming increasingly popular due to their simplicity, durability, and efficiency. However, choosing the right gearing for your bike can be a challenge, as there are many different factors to consider.
Types of Gearing
There are two main types of gearing for single speed gravel bikes: fixed gear and freewheel.
Fixed gear bikes have a fixed gear ratio, which means that the pedals are always moving in the same direction as the wheels. This can be a great option for riders who want a simple and efficient bike, but it can also be a challenge to ride on hills.
Freewheel bikes have a freewheel, which allows the pedals to move independently of the wheels. This makes it easier to ride on hills, but it can also be less efficient than a fixed gear bike.
Choosing the Right Gearing
The right gearing for your single speed gravel bike will depend on a number of factors, including your fitness level, the terrain you will be riding on, and your personal preferences.
If you are new to single speed gravel biking, it is a good idea to start with a lower gear ratio. This will make it easier to climb hills, but it will also be less efficient on flat terrain.
As you get more experienced, you can experiment with higher gear ratios. This will make your bike more efficient on flat terrain, but it will also be more difficult to climb hills.

Components of Single Speed Gravel Bike Gearing
A single speed gravel bike gearing system consists of three main components: the chainring, the cog, and the chain.
The chainring is attached to the bike’s crankset and is the gear that drives the chain. The cog is attached to the rear wheel and is the gear that the chain engages with.
Chainring
Chainrings come in a variety of sizes, with the most common sizes ranging from 32 to 42 teeth. The size of the chainring will determine the gear ratio of the bike, which is the ratio of the number of teeth on the chainring to the number of teeth on the cog.
A smaller chainring will result in a lower gear ratio, which is easier to pedal but will provide less speed. A larger chainring will result in a higher gear ratio, which is harder to pedal but will provide more speed.
Cog
Cogs also come in a variety of sizes, with the most common sizes ranging from 11 to 28 teeth. The size of the cog will also affect the gear ratio of the bike.
A smaller cog will result in a higher gear ratio, which is harder to pedal but will provide more speed. A larger cog will result in a lower gear ratio, which is easier to pedal but will provide less speed.
Chain
The chain is the component that connects the chainring to the cog. Chains are typically made of steel or titanium and come in a variety of lengths.
The length of the chain will depend on the size of the chainring and the cog. It is important to use the correct length of chain, as a chain that is too short will not be able to engage with the cog properly, and a chain that is too long will be more likely to derail.
Gearing Options
Single speed gravel bikes offer various gearing options to cater to different riding styles and terrain. These options include gear ratio, tooth count, and wide-range versus close-range gearing.
Gear ratiorefers to the relationship between the number of teeth on the front chainring and the rear cog. A higher gear ratio indicates a harder gear, while a lower gear ratio indicates an easier gear. The gear ratio is calculated by dividing the number of teeth on the chainring by the number of teeth on the cog.
Tooth Count
The tooth countof the chainring and cog determines the gear ratio. A larger chainring or a smaller cog results in a higher gear ratio, while a smaller chainring or a larger cog results in a lower gear ratio. The tooth count of the chainring and cog should be carefully selected to provide an appropriate range of gears for the intended riding conditions.
Wide Range vs. Close Range Gearing
Wide-range gearingprovides a greater range of gears, allowing the rider to tackle steep climbs and maintain a comfortable cadence on flat terrain. However, wide-range gearing can result in larger jumps between gears, which can make it difficult to find the optimal gear for certain situations.
Close-range gearingprovides a narrower range of gears, but with smaller jumps between gears. This makes it easier to find the optimal gear for the riding conditions, but it may limit the rider’s ability to tackle steep climbs or maintain a high speed on flat terrain.
Selecting the Right Gearing
Selecting the appropriate gearing for your single-speed gravel bike is crucial to ensure a comfortable and efficient ride. Consider your riding style, terrain, and fitness level when making this decision.
For flat or gently rolling terrain, a lower gear ratio (e.g., 32×18) will provide easier pedaling and allow you to maintain a higher cadence. Conversely, for hilly or mountainous terrain, a higher gear ratio (e.g., 36×21) will provide more torque to help you climb efficiently.
Gear Ratio Calculation
To calculate your gear ratio, divide the number of teeth on your chainring by the number of teeth on your rear cog. For example, a 32-tooth chainring and an 18-tooth cog would result in a gear ratio of 32/18 = 1.78.
Choosing the Right Gear Ratio
Consider the following factors when choosing the right gear ratio for your single-speed gravel bike:
- Terrain:Flat or rolling terrain requires a lower gear ratio for easier pedaling, while hilly or mountainous terrain requires a higher gear ratio for climbing efficiency.
- Riding Style:If you prefer a higher cadence, choose a lower gear ratio. If you prefer a more relaxed pace, choose a higher gear ratio.
- Fitness Level:If you are a beginner or have a lower fitness level, consider a lower gear ratio for easier pedaling.
Advantages and Disadvantages
Single speed gravel bike gearing offers both advantages and disadvantages that should be carefully considered before making a decision. Understanding these factors will help you determine if a single speed setup is right for your riding style and terrain.
Benefits of Simplicity and Reliability
- Simplicity:Single speed bikes eliminate the need for multiple gears, shifters, and derailleurs, resulting in a simpler and lighter drivetrain. This reduces maintenance requirements and the potential for mechanical issues.
- Reliability:With fewer moving parts, single speed bikes are generally more reliable and less prone to breakdowns. This is especially advantageous for riders who frequently venture into remote or rugged areas.
Limitations in Versatility and Efficiency
- Limited Versatility:Single speed bikes lack the versatility of geared bikes, which can adjust their gear ratios to suit different terrains and riding conditions. This can be a disadvantage on hilly or mixed-terrain rides where varying resistance levels are encountered.
- Reduced Efficiency:Single speed bikes may not be as efficient as geared bikes on certain terrains. For example, on steep climbs, a single speed bike may require more effort to pedal, while on descents, it may not be able to take full advantage of the momentum gained.
Maintenance and Troubleshooting
Maintaining and troubleshooting single speed gravel bike gearing is crucial for optimal performance and longevity. Regular maintenance can prevent issues and extend the lifespan of components.
Here are some essential tips for maintenance and troubleshooting:
Proper Chain Maintenance
- Clean the chain regularly to remove dirt and grime. Use a chain cleaner and a soft brush to gently scrub away any debris.
- Lubricate the chain after cleaning. Apply a thin layer of chain lube to the links and rollers to reduce friction and wear.
- Inspect the chain for wear and stretch. If the chain is stretched or has worn links, it should be replaced to prevent premature wear on other components.
Adjusting the Chain Tension
- Proper chain tension is essential for smooth shifting and efficient pedaling. Adjust the chain tension by loosening or tightening the rear wheel axle nuts.
- The chain should have a slight amount of slack when in the largest cog. If the chain is too tight, it can cause excessive wear on the chain and other components.
- If the chain is too loose, it can slip off the cogs, causing damage to the chain and cassette.
