Changing gears on a 21 speed mountain bike can be a daunting task for new riders. However, with the right technique and practice, you can efficiently shift your gears on the trails and enjoy a smoother ride. Knowing how to use your gears will also help you climb hills with ease and maintain a consistent speed on different terrain.
In this article, we will provide you with a step-by-step guide on how to shift gears on a 21 speed mountain bike. We will cover the basics of gear ratios, when to shift gears, and the proper technique for shifting up and down. By following these tips, you will be able to confidently tackle any trail and enjoy the exhilarating feeling of riding your mountain bike to its full potential.
Understanding the Basic Components of a 21 Speed Mountain Bike
When it comes to effectively changing gears on a 21 speed mountain bike, it’s essential to understand the basic components of the bike first. These components include the chain, shifters, derailleurs, and cassette. The chain runs from the front chainrings to the cassette at the rear wheel, with the shifters being located on the handlebars and connected to the derailleurs.
The derailleurs are mechanisms that move the chain across the cassette, allowing the rider to change gears, and the cassette contains the individual cogs of the bike. Understanding how these components work together is essential for efficient gear-changing and smooth riding. Taking the time to familiarize yourself with your bike’s components can also help you troubleshoot potential issues that may arise during a ride, such as a chain slipping or difficulty changing gears.

Choosing the Right Gear for Your Riding Conditions
When it comes to riding a 21 speed mountain bike, choosing the right gear for your riding conditions is crucial to ensuring a smooth and efficient ride. The gear ratio can impact your speed, power, and endurance, so it’s important to assess the terrain and adjust gear accordingly.
If you’re riding on smooth, flat terrain, it’s best to aim for higher gears to achieve a faster speed with less resistance. On the other hand, if you’re tackling a steep uphill climb, a lower gear will give you more power and control to pedal up the slope without exerting too much effort. Similarly, when you’re descending a steep slope, choosing a higher gear can allow you to maintain speed without losing control. By being mindful of your surroundings and choosing the right gear, you can effectively optimize your ride and improve your overall performance.
How to Shift Gears: Step-by-Step Guide
Shifting gears can be a critical aspect of mountain biking, as it helps to maintain a comfortable speed and slope when navigating through rough terrains. The following step-by-step guide outlines an efficient way of shifting gears on a 21-speed mountain bike.
Firstly, locate the gear shifters on your bike. These are usually found on the right side of the handlebars, and may be labelled as ‘up’ and ‘down’ or ‘high’ and ‘low.’ When in a comfortable riding position, use your right thumb to push the gear shifter upward to increase resistance or downward to decrease resistance. Ensure that you keep pedalling to facilitate a smooth transition between gears and avoid any sudden jerking movements. Practice shifting gears smoothly and efficiently on flat grounds before attempting to do so on slopes or hills, and always anticipate the terrain ahead to prepare for necessary gear changes. mastering gear shifting on a mountain bike can significantly enhance your overall biking experience, allowing you to tackle rough terrains and steep inclines with greater ease and confidence.

Tips to Ensure Smooth Gear Changes
To ensure smooth gear changes, it is crucial to maintain proper bike chain tension. A loose chain can cause gears to skip, while a tight chain will make shifting gears difficult. To adjust tension, loosen the rear axle nuts slightly and move the wheel backward or forward until there is about a 1/2 inch of slack on the bottom of the chain when in the smallest gear.
Another factor to consider is the cadence or the rate at which you pedal. Try to maintain a steady cadence while shifting gears to keep the chain moving smoothly. Shifting into higher gears too quickly can result in a jarring motion that can damage your bike’s chain or derailleur. Additionally, transitioning to lower gears should occur gradually to avoid straining the chain. With some practice and patience, mastering smooth gear changes on a 21-speed mountain bike is an achievable feat.
Common Mistakes to Avoid While Changing Gears
Common Mistakes to Avoid While Changing Gears
Changing gears on a mountain bike can be a tricky task, especially if you are new to it. It is quite normal to make mistakes while changing gears, but some mistakes can cause serious problems. Here are some common mistakes that you should avoid while changing gears on your 21-speed mountain bike.
The first mistake that many beginners make is shifting gears while pedaling hard. This can cause serious damage to the chain and the derailleur. You should always reduce your pedaling cadence before shifting gears. Another common mistake is shifting gears while standing on the pedals. This puts a lot of pressure on the chain and the derailleur, and it could lead to them getting damaged. You should always shift gears while sitting down. Lastly, avoid cross-chaining, which is when you use the largest front chainring with the largest rear cog or the smallest front chainring with the smallest rear cog. It causes the chain to run at an angle that puts extra stress on the chain and derailleurs, which could damage them over time.
Maintenance Tips for Smooth Gear Changes
Regular maintenance of your mountain bike is essential to ensure smooth gear changes. Here are some maintenance tips to keep in mind:
1. Keep your bike clean: Dirt, debris, and grime can get into your chain and derailleur, leading to poor shifting performance. Give your bike a good wash after each ride, and lubricate the chain regularly.
2. Monitor chain wear: A worn chain can negatively impact shifting quality. Use a chain wear gauge to measure the wear on your chain, and replace it as needed.
3. Check your cables: Over time, cables can stretch and become less effective. Check your cables for damage and fraying, and adjust or replace them if necessary.
By following these maintenance tips, you can ensure that your mountain bike’s gears are always shifting smoothly, allowing you to enjoy a more comfortable and efficient ride.

Advanced Techniques to Enhance Your Shifting Abilities on a 21 Speed Mountain Bike
Advanced Techniques to Enhance Your Shifting Abilities on a 21 Speed Mountain Bike:
1. Pre-shifting: This technique involves shifting gears just before you reach a section of the trail where you will need to change gears. This way, you will be ready for the upcoming climb or descent without any delay. Pre-shifting is essential for maintaining a smooth and consistent ride.
2. Synchro-shift: Synchro-shift is a technique where the front and rear derailleurs are synchronized, allowing for more consistent shifting. This technique can be activated by installing a compatible electronic groupset and can be done on the fly depending on the terrain. The system will automatically make minor front and rear derailleur adjustments to make for the smoothest shifting possible, eliminating the guesswork from the rider. With the synchro-shift technique, you’re also less likely to drop your chain.
Final Thoughts
Changing gears on a 21 speed mountain bike may seem daunting at first, but with practice, it becomes second nature. Remember to shift gears before you reach a hill or change in terrain, and adjust to a comfortable pace. Use the front derailleur to make larger gear changes and the rear derailleur for smaller adjustments.
In summary, follow these steps to change gears on a 21 speed mountain bike: anticipate changes in terrain, adjust to a comfortable pace, use the front derailleur for larger changes, and the rear derailleur for smaller ones. Whether you’re cruising on flat terrain or climbing hills, your mountain bike’s gears can help you maintain a smooth and efficient ride. Happy trails!
