Mountain Bike Gears Explained

There are typically two types of mountain bike gears: derailleur and hub. Derailleur gears are the most common, and they work by moving the chain between different-sized cogs on the rear wheel. Hub gears are less common, but they offer a more reliable drivetrain because the gears are sealed inside the rear hub.

Mountain bikes typically have anywhere from 7 to 12 gears, with most bikes having 9 or 10. The number of Gears is determined by multiplying the number of front chainrings by the number of cogs on the rear wheel. For example, a bike with 2 front chainrings and 9 cogs on the rear wheel would have 18 total gears (2×9=18).

The gear ratio is determined by the number of teeth on each cog divided by the number in front or behind it. For example, if you have a 24-tooth cog in front of a 36-tooth cog, your gear ratio would be 1.5 (24/36=1.5). A higher gear ratio means it’s easier to pedal, while a lower gear ratio makes it harder to pedal but easier to go faster.

Mountain biking is a sport that requires a lot of strength and endurance. In order to be successful, it is important to have the right gear. Here are some mountain bike gears explained:

The most important piece of gear for mountain biking is the bike itself. There are many different types of bikes available, but not all of them are suitable for mountain biking. It is important to choose a bike that is specifically designed for this type of riding.

The next most important piece of gear is the helmet. A helmet will protect your head in case of an accident and can also help keep you cool while you ride. Another important piece of gear is a pair of mountain bike gloves.

These gloves will help you grip the handlebars and will also protect your hands from being scratched by branches or other objects on the trail. Mountain bike shoes are also very important. They should be comfortable and provide good traction so that you can keep your feet planted on the pedals when going downhill.

What Gears Should I Use on My Mountain Bike?

There is no definitive answer to this question as it will vary depending on the terrain you are riding on, your personal preferences, and the type of mountain bike you are using. However, as a general guide, if you are riding on relatively flat terrain or moderate inclines, you should be using lower gears. If you are riding on more challenging terrain with steep inclines, then you will need to use higher gears.

Is Gear 1 High Or Low on a Bike?

In most cases, gear 1 on a bike is considered to be low. This is because it is the easiest gear to pedal in and requires the least amount of effort to maintain a consistent speed. Additionally, gear 1 is often used when starting from a stopped position or when climbing hills.

When Should I Shift My Mountain Bike Gears?

When you are mountain biking, it is important to shift your gears in order to maintain optimal pedaling efficiency. You should shift your gears based on the terrain you are riding on and how fast you are going. If you are riding on flat or gentle terrain, you will want to use lower gear.

This will help you pedal more efficiently and avoid overworking your legs. If you are riding uphill, you will want to use a higher gear in order to make pedaling easier. And if you are riding downhill, you will want to use a lower gear so that you can control your speed better.

You should also shift gears based on how fast you are going. If you are pedaling slowly, you will want to be in lower gear. But if you are pedaling quickly, you will want to be in higher gear.

There is no one perfect speed for shifting gears, so experiment until you find what works best for you. In general, it is best to practice shifting gears before heading out onto the trails. That way, you can get comfortable with how your bike responds and learn what shifting patterns work best for different types of terrain and speeds.

How Do You Use Different Gears on a Mountain Bike?

There are a few things to consider when shifting gears on a mountain bike. First, you’ll need to know how many gears your bike has. Most mountain bikes have either 27 or 30 gears.

The next thing to think about is what gear you’re in currently and what gear you want to be in. To make shifting easier, it’s helpful to think of your gears in terms of low, middle, and high. Low gears are good for climbing hills or riding into the wind, while high gears are better for downhill riding or sprinting.

To shift up into a higher gear, you’ll need to pedal faster. To shift down into a lower gear, you can either pedal slower or use your brakes to slow down the pedals (which will also make shifting easier). When shifting, it’s important not to put too much pressure on the pedals as this can damage the chain.

Instead, just let off the pressure briefly as you shift Gears should always be shifted one at a time so that they can engage properly. Mountain biking is a fun way to get outdoors and explore different terrain. By learning how to use your bike’s gears correctly, you can make sure that your rides are enjoyable and safe!

21 Speed Bike Gears Explained

If you’re new to road biking, or even if you’ve been riding for a while, the sheer number of gears on your bike can be daunting. How do you know when to shift? What’s the difference between all those cogs anyway?

Here’s a basic rundown of what you need to know about shifting gears on your 21-speed bike. The vast majority of road bikes have two shifters, one on the left handlebar that controls the front derailleur and one on the right that controls the rear. Each shifter has two positions: up and down.

To shift into a higher gear (i.e. make pedaling easier), push the appropriate lever down. For example, to shift from the small chainring in front to the middle ring, push the left shifter down. To shift into a lower gear (i.e. make pedaling harder), do the opposite: push the levers up.

So shifting from the middle ring to the large ring would require pushing your left shifter up. It’s important to note that you should only ever shift one gear at a time on either derailleur; if you try to go from small chainring straight to large, or vice versa, you’ll likely end up damaging your drivetrain. Instead, always go through the middle ring first – this is called trimming your gears.

On most 21-speed bikes, there are seven sprockets in the back and three chainrings in front; this is referred to as a 7×3 drivetrain configuration. Your cassette (the name for your cluster of rear sprockets) will usually have either an 11-25 or 12-28 tooth range; these numbers refer to how many teeth are on each cog in the back, with larger numbers indicating easier gears and smaller numbers indicating harder gears. Likewise, your chainrings will be labeled with something like 34-50-64; again, bigger numbers mean easier gears while smaller ones are harder.

Most riders will find themselves using just a few different combinations of these gears depending on terrain and their own fitness level; it’s rare that anyone uses all 21 speeds in one ride!

18-Speed Bike Gears Explained

If you’ve ever wondered how those 18 speeds on your bike are determined, or what exactly “low gear” and “high gear” mean, this post is for you! We’ll give a brief overview of bike gears and how they work to help you better understand how to use them. First, it’s important to know that there are two types of bike gear: derailleur gears and hub gears.

Derailleur gears are the most common type found on road bikes and mountain bikes. They consist of two sprockets (chainrings) in the front and up to 11 sprockets (cogs) in the back, all connected by a chain. Hub gears are less common but can be found on some city bikes and touring bikes.

They’re enclosed within the rear wheel hub and usually have just 3 or 7 speeds. The number of speed options on a bike refers to the total number of combinations of front and rear sprockets that the chain can be run through – so 18 speed means 2 x 9 speed. The vast majority of 18-speed bicycles have two chainrings in the front (mounted on the crank arm), giving you low gear (a smaller ring) for climbing hills or riding into headwinds, and high gear (a bigger ring) for going fast downhill or with a tailwind.

The size difference between these two chainrings will determine your gearing range. For example, if your large chainring has 52 teeth and your small one has 36 teeth, then your gearing range would be 52/36 = 1.44 :1 – meaning that every turn of the pedals will rotate the rear wheel 1.44 times. The cogs at the back also come in different sizes, typically ranging from 11-25 teeth although some higher-end cassettes can go up to 34 teeth.

These smaller numbers refer to easier gearing because they offer less resistance to pedaling – so an 11-tooth cog is easier than a 25-tooth cog because it takes less effort to turn over 11 teeth than 25 teeth when you’re pedaling at a cadence (the rate at which you’re turning over the pedals).

7 Speed Bike Gears Explained

Are you looking to buy a new bike, but overwhelmed by all of the different gear options? Do you already have a bike but aren’t quite sure how to use all of the gears? This blog post is for you!

We’ll go over the basics of what bike gears are and how to use them. Bike gears are essentially just like the gears on a car – they help you go faster or slower, depending on which gear you’re in. On a bike, there are usually two sets of gears the front set (also called chainrings) and the rear set (known as cogs).

Most bikes will have either 2 or 3 chainrings up front, and anywhere from 7-11 cogs in the back. The combination of these two factors will determine how many total speeds your bike has. For example, if your bike has 3 chainrings and 11 cogs, it’s a 21-speed bike.

When shifting gears on a bike, you’ll always want to shift both sets at the same time. So if you’re shifting from one chainring to another upfront, be sure to also shift the corresponding cog in the back. This will keep your chain from getting tangled or caught on anything.

It’s also important to note that you shouldn’t ever cross-chain – meaning having your chain on either the outermost or innermost ring in front, and also either the outermost or innermost cog in back. This puts too much stress on your drivetrain and can cause damage. Now that we’ve gone over some basics, let’s talk about when and why you would want to shift gears while riding.

In general, you’ll want to be in a higher gear when riding uphill or into headwinds (since pedaling will be more difficult), and in a lower gear when going downhill or with tailwinds (since pedaling will be easier). You’ll also want to shift frequently when starting off from a stop – it’s better to start in low gear so that you don’t strain yourself as you get up to speed. And finally, if you’re ever feeling like you’re pedaling too hard for how fast you’re going (i.e. if your legs feel like they’re about to explode!), simply shift into an easier gear so that pedaling becomes easier again.

Mountain Bike Gears Explained Reddit

Mountain biking is a great way to get outdoors and enjoy some exercise, but it can be daunting if you’re not familiar with the gear involved. Here’s a quick explanation of mountain bike gears to help you get started. Most mountain bikes have between 21 and 27 gears, which are controlled by shifters on the handlebars.

The number of gears is determined by the number of front chainrings (usually 2 or 3) and the number of cogs on the rear cassette (usually 7-11). The front chainrings are responsible for most of the pedaling power, while the rear cogs provide finer control over speed. shifting between different combinations of front and rear gears allows you to maintain a comfortable pedaling cadence while riding up or down hills.

To shift gears, you’ll use your left hand to control the front derailleur (which moves the chain between front chainrings) and your right hand to control the rear derailleur (which moves the chain between cogs on the cassette). Most mountain bikes have trigger shifters, which allow you to click through each gear sequentially with your index finger. When shifting gears, it’s important to avoid cross-chaining, which occurs when the chain is in an extreme position on either side of the drivetrain (e.g., a small cog in the back with a large ring in front, or vice versa).

Cross-chaining puts unnecessary strain on both your drivetrain components and your legs, so it’s best to avoid it if possible. Instead, try to keep your chain relatively straight as you pedal. With a little practice, shifting gears will become second nature and you’ll be able to tackle any trail thrown your way!


In conclusion,mountain bike gears explain how they work. They work by using a cog/ cassette to turn a gear in the bike’s crankset. A higher gear allows you to pedal harder and with more power, while a lower gear creates a slower speed and less power.
