What Do Bike Cassette Numbers Mean?

The numbers on a bike cassette refer to the gears, with the larger numbers representing the easier gears for pedaling up hills and the smaller numbers being the harder gears for going downhill or sprinting. The number one gear is typically the hardest gear on a bike.

Bike cassettes come in a wide range of sizes, from small 11-25t options up to massive 12-speed 52t variants. The number on your bike cassette indicates the smallest sprocket size, while the largest is determined by the number of teeth on your chainring. For example, an 11-25t cassette has teeth counts of 11, 13, 15, 17, 19, 21, 23, and 25 on the sprockets.

A 12-speed 52t option would have teeth counts of 10, 12, 14, 16, 18, 20, 22, and 24 on the sprockets (therefore requiring a larger freehub body). The vast majority of road bikes will come equipped with a cassette somewhere between 11-28t and 11-32t. The smaller end of that spectrum is more suited to climbing hills due to the easier gears it provides, while the larger end is designed for flat terrain or time trialing where speed is more important than cadence.

In general, if you’re looking for a fast bike then you’ll want a 32t maximum, while if you’re looking for an endurance setup then something like 28t will suffice. There are some riders who even go as high as 34t or 36t for their big ring setups! So, what do those numbers mean?

Well, quite simply put – they indicate how easy or difficult it will be to pedal. The higher the number, the harder it will be to turn those pedals over and vice versa. This is because there are fewer teeth engaged with the chain at any one time, meaning less mechanical advantage.

What Does an 11-32 Cassette Mean on a Bike?

An 11-32 cassette means that the bike has 11 gears in the back and 32 teeth on the biggest cog. This is a common gear ratio for road bikes. Having 32 teeth on the biggest cog gives you lower gear for climbing hills.

having 11 gears in the back of the bike gives you more options when shifting than having fewer gears.

Does the Number of Teeth on a Cassette Matter?

When it comes to cassettes, the number of teeth on the cassette does matter. The higher the number, the more difficult it is to pedal. For example, a cassette with 36 teeth will be harder to pedal than one with 34 teeth.

The reason for this is that the larger chainring on a 36-tooth cassette has more surface area, which means that there is more resistance when pedaling. This resistance can make it difficult to maintain a high cadence, or pedaling speed. If you are looking for an easier gear to help you climb hills or ride longer distances, then you may want to consider a smaller chainring size.

What Does 12 28 Cassette Mean?

A cassette is a type of cartridge used to hold recorded media in an audio device, such as a tape recorder or radio. The term “cassette” is also used to refer to the tapes themselves. Cassettes come in different sizes, with the most common being 12 28 cassettes.

What Does 12 25 Cassette Mean?

When it comes to bike cassettes, the numbers 12 and 25 refer to the number of teeth on the two smallest cogs. So a 12-25 cassette has 12 teeth on its smallest cog and 25 teeth on its next largest cog. This particular cassette size is often used by road cyclists who are looking for a wide range of gear.

The smaller 12-tooth cog provides a higher gear for when you need to pedal fast, such as when you’re going downhill or trying to sprint. The larger 25-tooth cog gives you a lower gear for when you need more torque, such as when you’re climbing a hill. Having this range of gears allows you to spin your legs faster or slower depending on the terrain and how much power you want to generate.

If you’re not sure what size cassette is right for you, it’s best to consult with your local bike shop or an experienced cyclist. They’ll be able to help you choose based on your riding style and the type of terrain you’ll be riding on most often.

Bike Cassette Explained

A bike cassette is a stack of metal cogs that attaches to the rear wheel of a bicycle and drives the chain. The term “cassette” can also refer to the complete assembly including the freehub body, to which the cogs fit. The number of cogs on a bike cassette varies, but most cassettes have between 9 and 12 cogs.

The smallest cog is typically attached to the freehub body, while the largest cog is usually mounted on an aluminum or steel carrier that threads onto the freehub body. In between these two extremes are cogs of various sizes that provide different gear ratios when paired with the chainring on the front crankset. Bike cassettes come in two basic varieties: freewheel and screw-on.

Freewheel cassettes thread onto a threaded hub shell and use a lockring to secure all of the cogs in place. Screw-on cassettes do not require a lockring as they attach directly to special hubs that have splines instead of threads. These hubs are known as “freehubs.”

The vast majority of modern bikes use screw-on cassettes because they offer several advantages over freewheels. First, it’s easier to remove and install screw-on cassettes without specialized tools. Second, you can change out just one cog at a time if you wear out one before the others.

Third, because they don’t rely on friction between mating parts (threads) for stability, screw-on cassettes tend to be more durable than freewheels.

How Do I Know What Cassette is on My Bike

If you’re like most cyclists, you probably don’t give your bike’s cassette much thought – until it starts making strange noises or skipping gears. Then, all of a sudden, you need to know what kind of cassette is on your bike! There are a few different ways to figure out what kind of cassette is on your bike.

The first and easiest way is to look at the markings on the cassette itself. Most cassettes will have either an identification code (like “Shimano 10-speed HG50”) or the number of teeth on each cog clearly marked. If there are no markings on the cassette, or you can’t make them out, you’ll need to remove the cassette from the wheel to take a closer look.

This is easiest with a Park Tool Cassette Lockring Removal Tool (or similar). Once the lockring has been removed, the cogs can be separated from one another. Counting the number of cogs will tell you how many speeds your bike has (e.g., 9-, 10-, 11-speed), while looking at the teeth on each cog will give you an idea of which range they belong to (e.g., Shimano Ultegra 11-25T vs SRAM PG-1070 11-36T).

Knowing which type of cassette is on your bike can be helpful when buying replacement parts or upgrading components. It’s also just good general knowledge to have about your bicycle!

11-34 Cassette on Road Bike

When it comes to road bikes, there are a few different cassette options that you can choose from. One popular option is the 11-34 cassette. This particular cassette offers a wide range of gears, which can be great for climbing hills or riding on flat terrain.

Here is some more detailed information about the 11-34 cassette: The 11-34 cassette offers 11 gears in total. The smallest cog has 11 teeth and the largest cog has 34 teeth.

This gives you a lot of options when it comes to finding the right gear for your ride. One thing to keep in mind with this particular cassette is that it does require a longer chain than some other cassettes. So, if you are switching from another type of cassette, make sure you have the correct chain length.

This type of Cassidy also works best with Shimano shifters. If you have SRAM shifters, you may need an adapter in order to use this Cassidy. Overall, the 11-34 Cassidy can be a great option for those looking for a wide range of gear on their road bike.

Just make sure you keep in mind the requirements (such as chain length) before making the switch!

Shimano Cassette Sizes

Shimano makes several different types and sizes of cassettes. The most common size is the Shimano 10-speed cassette. This size is compatible with all Shimano drivetrains and many other brands as well.

The next most popular size is the Shimano 11-speed cassette. This site requires a special freehub body but otherwise works with all Shimano drivetrains. There are also 12, 13, 14, and 15-speed cassettes available from Shimano, although these are less common.

The vast majority of Shimano cassettes will fit on any standard road or mountain bike hub. The only exception to this rule is the new 12-speed XTR cassette, which requires a special micro spline freehub body. Other than that, any Shimano cassette will work with any Shimano drivetrain.

There are three main types of cassettes offered by Shimano: road, mountain, and cross-country/enduro. Road cassettes tend to be lighter in weight and have narrower gears for higher speeds. Mountain cassettes are designed for durability and have wider gears for climbing hills.

Cross-country/enduro cassettes fall somewhere in between road and mountain in terms of weight and gearing ratio. If you’re unsure which type or size of the cassette is right for you, your best bet is to consult your local bike shop or search online for more specific advice.

Conclusion

Bike cassettes are the gears that attach to the back wheel of a bicycle. They come in a variety of sizes, which are indicated by numbers. The most common size is 10-speed, but there are also 11- and 12-speed options.
