Are Bicycle Pedal Threads Universal?

No, they are not.

Most bicycle pedals use 9/16-inch x 20tpi threads, which are the most common size. There are however, a few different sizes in use. The other common size is 1/2-inch x 20tpi. These are most often found on BMX bikes and some lower-end mountain bikes.

French-threaded pedals use a different threading, which is not compatible with either of the above. The French threading is rarely used on new bikes, but you may come across it if you ride an older French bike.

Are Bicycle Pedal Threads Universal?

Bicycle pedal threads are not universal. There are two different types of threads, metric and standard. Metric threads are most common in Europe, while standard threads are most common in the United States.

If you’re unsure which type of thread your bike has, you can measure the diameter of the thread with a ruler or a caliper. If the diameter is 9mm, then it’s a metric thread. If the diameter is 3/8″, then it’s a standard thread.

If you’re buying new pedals, make sure to get the right type of pedal for your bike. You can usually find this information on the pedal’s packaging.

If you have a bike with metric threads and you want to use standard pedals (or vice versa), you can get an adapter. This is a small piece of metal that goes between the pedal and the crank arm. You can find adapters at most bike shops.

What Is The Difference Between Universal And Non-universal Pedal Threads?

Non-universal pedal threads refer to a specific type of pedal threading that is not compatible with all types of bike pedals.

If you’re a beginner cyclist or new to bike maintenance, you might not know the difference between universal and non-universal pedal threads. It’s actually a pretty simple concept, but it’s important to know the difference so you can be sure to get the right pedals for your bike.

Universal pedals have a standard threading that will work with most bike cranks. Non-universal pedals have a specific threading that is only compatible with certain cranks. So, if you have a non-universal pedal and try to put it on a different kind of crank, it probably won’t work.

Now that you know the difference, let’s take a look at an example. Say you have a road bike with Shimano 105 pedals. You want to upgrade to Shimano Ultegra pedals, which are a little nicer. You might think that since both Shimano pedals are universal, you can just switch them out. But that’s not the case. The Ultegra pedals are actually non-universal, so they won’t fit on your 105 crankset. You would need to get a new set of pedals and new crankset that are both compatible with Ultegra pedals.

So, when you’re shopping for pedals, be sure to pay attention to whether they’re universal or non-universal. That way, you can be sure to get the right pedals for your bike.

Why Are Some Pedals Threaded And Some Not?

So that they can be screwed onto the crank.

It’s a common question that stumps even the most experienced cyclists. After all, pedals are one of the most essential parts of a bike, so it’s important to know how they work. Here’s a quick explanation of the difference between threaded and unthreaded pedals.

Threaded pedals have a screw thread that screws into the crank arm. This type of pedal is common on older bikes and is still used on some modern bikes. The main advantage of threaded pedals is that they’re very securely attached to the bike. However, they can be difficult to remove if you need to make a quick repair or adjustment.

Unthreaded pedals, on the other hand, simply attach to the crank arm with a nut and bolt. This type of pedal is more common on modern bikes and is considered to be more user-friendly. Unthreaded pedals are easier to remove and install, which can be handy if you’re making on-the-fly repairs or adjustments.

So, which type of pedal is right for you? It really depends on your personal preference. If you’re looking for a more secure attachment, go with threaded pedals. If you want an easier installation, go with unthreaded pedals.

How Do I Know If My Pedals Are Threaded?

If your pedals are threaded, you will be able to screw them onto the crank arms.

If you’re new to riding, or just new to bike maintenance, you might not know how to tell if your pedals are threaded. Here’s a quick guide to help you out.

First, take a close look at your pedals. If they have a hole in the center, they’re most likely threaded. Unthreaded pedals will usually have a solid center.

To be sure, you can also try screwing a pedal into the crank arm. If it’s threaded, it will screw on easily. If not, you’ll feel resistance or it might not screw on at all.

Once you know your pedals are threaded, you can install them using a pedal wrench or a hex key. If you don’t have either of those tools, you can usually use a regular wrench or a socket set.

Just screw the pedals in until they’re tight, but be careful not to over-tighten them. You don’t want to strip the threads.

And that’s all there is to it! Now you know how to tell if your pedals are threaded, and how to install them.

Can I Use Any Pedals On My Bike?

It’s a common question, and one with a simple answer: yes, you can use any pedals on your bike.

There are a few different types of pedals, but the two most common are flat pedals and clipless pedals. Flat pedals are the type with a flat surface that you can rest your foot on. Clipless pedals are the type that you clip your shoes into.

Which type of pedal you use is up to you. Some people prefer flat pedals because they’re easy to get in and out of and they offer more stability. Others prefer clipless pedals because they’re more efficient and offer a more secure connection to the bike.

If you’re not sure which type of pedal to use, try both and see which one you prefer. There’s no right or wrong answer, it’s all about what works best for you.

Here’s a quick rundown of the different types of pedals and what they have to offer:

Flat pedals:

– Easy to get in and out of

– More stable than clipless pedals

– Can be used with any type of shoe

– typically less expensive than clipless pedals

Clipless pedals:

– More efficient than flat pedals

– Offer a more secure connection to the bike

– Can be used with special cycling shoes

– More expensive than flat pedals

So, there you have it. You can use any pedals on your bike, it’s just a matter of finding the right ones for you. Experiment and see what works best for you. There’s no wrong answer, so go forth and pedal!


What Are The Benefits Of Having Threaded Pedals?

Threaded pedals have a number of benefits over non-threaded pedals. First, they are much easier to keep tight on the crank arms. Second, they offer a much wider range of adjustment for cleat position. Third, they are less likely to come loose and fall off while riding. Finally, they are much easier to replace if they do wear out.

Are There Any Disadvantages To Having Threaded Pedals?

There are a few disadvantages to having threaded pedals. One is that they can be difficult to remove if they become seized on the crank arm. Another is that they are not compatible with some types of cleats. Finally, they can be more difficult to adjust than some other types of pedals.

What Happens If I Use Pedals That Are Not Threaded On My Bike?

If you use pedals that are not threaded on your bike, they will not be able to attach to the bike properly and could come loose while you are riding. This could cause you to lose control of the bike and possibly crash.

Is It Difficult To Change Pedals With Different Threading?

It is difficult to change pedals with different threading because the threads on the pedals are different sizes. The pedals also have different widths and heights, which can make it difficult to line up the holes in the pedals with the holes in the bike frame.


The vast majority of bicycle pedal threads are of the 9/16″ variety, with 1/2″ being much less common. There are a few other sizes in use, but they are much less common. As such, it is safe to say that 9/16″ is the de facto standard for bicycle pedal threads.
