11-28 Vs 11-30 Cassette Chain Length

If you have ever wondered if there is a difference between an 11-28 and an 11-30 cassette chain length, then this article is for you. We will take a look at the different sizes and see if one is better than the other.

If you’re a bike commuter, you know that one of the most important things to keep in mind is your chain length. Depending on the size of your chainring and cogset, you’ll need a different length chain. For example, an 11-28 cassette requires a longer chain than an 11-30 cassette.

Why does this matter? Well, if your chain is too short, it could come off while you’re riding and cause all sorts of problems (not to mention be really dangerous!). If it’s too long, it could get tangled up or rub on your frame.

Either way, it’s not good. So how do you know what length chain to get? The best way is to consult with your local bike shop or look up the specs for your particular bike online.

But as a general rule of thumb, an 11-28 cassette will require a longer chain than an 11-30 cassette. So if you’re unsure, err on the side of getting a longer chain. Better safe than sorry!

What is the Difference between 11-28 And 11 30 Cassette?

There are a few key differences between an 11-28 and 11-30 cassette. The most obvious difference is the range of gears, with the 11-30 offering more gears overall. This can be helpful if you ride in hilly or mountainous terrain where having a wider range of gears can make climbing easier.

Another difference is that the 11-30 cassette requires a longer chain, which may need to be replaced more often than on a bike with an 11-28 cassette. Finally, the 11-30 cassette may also require a different derailleur than the 11-28, so it’s important to check compatibility before purchase.

Do I Need to Change My Chain Length for Different Cassettes?

If you’re unsure whether or not you need to change your chain length for different cassettes, the best thing to do is consult your bike’s owner’s manual. In general, however, most bikes will require a longer chain when used with a cassette that has a larger range of gears (i.e. more teeth on the biggest sprocket). This is because the bigger cassette requires the chain to run at a greater angle over the sprockets, which puts more stress on the chain and can cause it to loosen or fall off if it’s not long enough.

Conversely, using a smaller cassette will usually require a shorter chain. There are also some specific cases where you might need to adjust your chain length even if you’re using the same size cassette – for example, if you switch from a road bike to a mountain bike frame that has slacker angles (which also increases the effective size of the cassette). Again, consulting your owner’s manual or taking your bike to a professional mechanic should help you determine whether or not this is necessary in your particular case.

Do I Need a Longer Chain for a Bigger Cassette?

If you’re wondering if you need a longer chain for a bigger cassette, the answer is maybe. It depends on the size of your current chain and the size of your bike’s drivetrain. A standard road bike has a 53/39 tooth setup, while a mountain bike typically has something smaller, like a 44/32 tooth setup.

The number of teeth on the front and rear sprockets determine how far the chain has to travel per revolution. So, if you have a larger cassette with more teeth (say, 11-25), then you will need a longer chain to accommodate that extra distance. But if you have the same number of teeth on both the front and rear sprockets (like 53/39), then you don’t necessarily need a longer chain – it just depends on how much slack your current chain has.

If it’s really tight, then going up one size might give you some needed wiggle room; if it’s really loose, then dropping down one size might be all that’s necessary. Ultimately, it comes down to trial and error – put together your dream drivetrain and see how it shifts. If it doesn’t work well, then adjust accordingly!

Is a 11/28 Cassette Good for Hills?

There’s no definitive answer to this question since it depends on a variety of factors, such as the steepness of the hills, your riding style, and the weight of your bike. However, in general, an 11/28 cassette is likely to be good for hills if you’re looking for a wide range of gears to choose from. This is because the 28t cog provides a low gear that can help you power up steep hills, while the 11t cog gives you a higher gear for when the gradient levels out.

Difference between 11-28 And 11-30 Cassette

If you’re a serious cyclist, then you know that there’s a big difference between an 11-28 and an 11-30 cassette. The bigger the cassette, the easier it is to pedal up hills. That’s because the cassette is like a gearbox on your bike, and the bigger gears make it easier to turn the pedals.

So if you’re looking to buy a new bike, or upgrade your existing one, be sure to pay attention to the size of the cassette. It can make a big difference in how easy (or difficult) it is to ride up hills!


If you’re wondering what chain length to get for your new bike, here’s a quick guide. For a 11-28 cassette, you’ll need a longer chain than for a 11-30 cassette. The extra two teeth on the 11-30 require about 3/32″ more chain, so make sure to get the right size.
