Will Any Derailleur Work With Any Cassette?

No, not every derailleur will work with every cassette. The reason for this is that each derailleur is designed to work with a specific range of gears, and each cassette has a different range of gears. If you try to use a derailleur with a cassette that has a different range of gears, the derailleur may not be able to properly shift the chain between the gears on the cassette.

No, not every derailleur will work with every cassette. The reason for this is that each derailleur has a specific range that it is designed to work with, and this range will be determined by the size of the cassette cogs. For example, if you have a 10-speed cassette, you’ll need a derailleur that’s designed for use with 10-speed cassettes.

There are some exceptions to this rule, however. Some newer 11-speed cassettes are compatible with both 11-speed and 10-speed derailleurs, and there are also some adapters available that can allow you to use a different size cogset with your existing derailleur. But in general, it’s best to stick with using the same size components throughout your drivetrain.

Does a Derailleur Need to Match the Cassette?

The quick answer is yes, a derailleur needs to match the cassette. But there’s a little more to it than that. Let’s take a closer look.

A derailleur is a device that moves the chain from one sprocket to another on your bike. It consists of two parts: the cage, which holds the chain, and the pulleys, which guide the chain. The cage must be wide enough to accommodate the largest sprocket on your cassette, and the pulleys must be spaced correctly so they can line up with all of the teeth on all of the sprockets.

If your derailleur doesn’t match your cassette, you may have problems shifting gears smoothly or at all. In extreme cases, mismatched components can cause your chain to come off entirely! So it’s important to make sure everything is compatible before you ride.

There are several different types of cassettes and derailleurs available on the market, so it’s important to do some research before making a purchase. Once you’ve found compatible parts, be sure to follow installation instructions carefully so everything works properly when you hit the road.

Does It Matter What Derailleur You Use?

There are a lot of factors to consider when purchasing a derailleur and one of the most important is compatibility. Different derailleurs are designed for different types of bikes and riding styles so it’s important to make sure you get the right one. The two main types of derailleurs are mountain bike derailleurs and road bike derailleurs.

Mountain bike derailleurs are typically wider than road bike derailleurs to accommodate for thicker chainrings. They also tend to have longer cages to accommodate longer chain stays. Road bike derailleurs typically have shorter cages since they’re not needed to accommodate as much chain length.

Mountain biking generally puts more stress on the drivetrain components, so mountain bike derailleurs are often beefier and made from tougher materials. They also usually have clutch mechanisms that help prevent the chain from bouncing around or falling off altogether. Road cycling tends to be smoother and less strenuous on drivetrain components, so road bike derailleurs can be lighter weight and doesn’t always need clutches.

One other factor that’s important to consider when choosing a derailed is actuation – this refers to how much cable pull is required to move the cage back and forth. Shimano uses what’s called “Shadow technology” in their mountain bike rear derailleurs which reduces the amount of cable pull needed, making shifting smoother and more precise, especially under load. SRAM uses a 1:1 actuation ratio across all of their groupsets (road and mountain), meaning that each millimeter of cable pull moves the cage one millimeter – this makes setting up simpler since you don’t need to adjust for different leverage ratios like with Shimano systems.

In general, it does matter what type of rear derailed you use because they perform differently based on the intended purpose/use case as well as having different levels of built-in durability & precision.

Do I Need a New Derailleur If I Change Cassette?

If you’re planning on changing your bike’s cassette, there’s a good chance you’ll need to replace your derailleur as well. Here’s a quick rundown of why this is the case: Most cassettes have different cog sizes, which means that the distance between each cog will be different.

This in turn affects the amount of chain slack, and thus the tension required to shift gears. A new cassette will likely require a different amount of tension than your old one, meaning that your current derailleur may not be able to properly shift into all the gears. In addition, many newer cassettes use a “closer” spacing between cogs.

This can put extra strain on your derailleur, potentially causing it to break or wear out more quickly. So if you’re planning on upgrading to a newer style of the cassette, it’s usually best to get a new derailleur at the same time. Of course, there are always exceptions to the rule.

If you know exactly what kind of cassette you’re getting and you’re confident that it won’t require any major changes to your shifting setup, then you might be able to get away with keeping your old derailleur. But in most cases, it’s best to err on the side of caution and pick up a new one before making any big changes to your bike’s drivetrain.

How Do I Know If a Derailleur Will Fit My Bike?

There are a few different ways to determine if a derailleur will fit your bike. One way is to look at the specifications of your bike frame and compare them to the derailleur. Another way is to measure the space between the mounting holes on your frame and compare that measurement to the maximum width of the derailleur.

The most important thing to consider when determining if a derailleur will fit your bike is compatibility with your shifters. Most mountain bikes use Shimano shifting components, so it’s important to make sure that the derailleur you’re considering is compatible with those components. You can usually find this information in the product description for the derailleur.

Once you’ve determined that the derailleur is compatible with your bike, you’ll need to make sure that it has enough clearance for all of the gears on your cassette. The easiest way to do this is to remove your rear wheel and measure from the centerline of the frame to the outer edge of the cassette. This measurement should be greater than or equal to the maximum width of the derailleur listed in its specifications.

Shimano Compatibility Chart 9-Speed

Shimano Compatibility Chart 9-Speed The Shimano 9-speed compatibility chart is a chart that shows which Shimano road components are compatible with each other. The chart is divided into four sections: shifters, derailleurs, cranksets, and bottom brackets.

Each section has a list of compatible components. For example, the shifters section lists the SL-BS64 10-speed bar end shifter as being compatible with the STI Dura Ace 9100 11-speed STI lever (SL-BS64 is listed in the column under SHIFTERS and STI Dura Ace 9100 is listed in the row under 11-SPEED STI LEVERS). The first thing to note about the chart is that it only applies to Shimano road components.

If you have a mix of Shimano and SRAM components, then you will need to consult both the Shimano compatibility chart and the SRAM compatibility chart. Also, keep in mind that not all combinations of Shimano components will work together. For example, you cannot use an 11-speed cassette with a 9-speed chain.

Here are some tips for using the Shimano compatibility chart: • Check both the column and row headers to find out what version of the component you have. For example, if you have an Ultegra 6500 rear derailleur, then check both the column header for 6500 and also look at all of the rows that say RD 6400/6500/6600 (these are different versions of Ultegra rear derailleurs).

Be aware that there may be more than one version of a particular component – for example, there are several different types of 105 cranksets. Make sure you check all options before assuming that a certain combination won’t work together. • When in doubt, consult your local bike shop or search online for more information about specific combinations of components.
