Mountain Bike Axels Explained: Common Types And Problems

There are many different types of mountain bike axels on the market, and each has its own advantages and disadvantages. In this article, we will take a look at the most common types of mountain bike axels and some of the problems that can occur with them.

What are the Different Types of Bike Axles?

There are three main types of bike axles: quick release, solid axle, and thru-axle.

Quick release axles are very convenient because they allow you to remove your wheel without having to use any tools. However, they are not as strong as other types of axles and can sometimes come loose during riding.

Solid axles are less common but are often found on BMX bikes and some mountain bikes. They’re simply a rod that goes through the hub and is threaded on both ends. Thru-axles are becoming more popular in recent years as they offer a stronger connection between the wheel and frame than quick release or solid axles.

Thru-axles are much stronger than quick release axles and provide a more secure connection between your wheel and frame. However, they can be more difficult to install and remove. Finally, there are bolt-on axles.

What Causes a Bike Axle to Break?

Bike axles are designed to withstand a certain amount of force. However, if too much force is applied to the axle, it can break. There are several reasons why this might happen:

1. The bike was involved in an accident. If the bike hits something hard enough, the force of the impact can break the axle.

2. The bike was ridden over rough terrain.

Again, the force of the bumps and jolts can eventually break an axle that isn’t designed for that type of riding.

3. The axle was not properly installed. This is most likely to happen if you try to install an aftermarket axle yourself without knowing what you’re doing.

Improper installation can put stress on the axle and cause it to break eventually.

4. The axle was defective from the factory. This is relatively rare, but it does happen occasionally.

If you suspect that your axle may be defective, take it to a qualified bike mechanic for inspection.

Problems that can occur with mountain bike axels:

There are two main problems that can occur with mountain bike axels: bending and breaking. Bending typically occurs when an impact is applied to the axle (such as hitting a rock or root), causing it to bend slightly out of shape. This can make it difficult to remove the wheel, as the bent axle will no longer line up correctly with the dropouts.

Breaking usually happens from repeated impacts or from an extremely hard impact (like crashing). A broken axle will need to be replaced before you can ride again. If you’re having trouble with your mountain bike’s axels, bring it into your local bike shop for help.

The mechanics there will be able to diagnose the problem and get you back on the trail in no time!

What is the Axle on a Bicycle Called?

The axle on a bicycle is the rod that runs through the center of the wheel, connecting it to the frame. The term “axle” can also refer to the entire assembly consisting of the axle, bearings, and hub.

How Do I Know If My Bike Has a Thru Axle?

If you’re unsure whether or not your bike has a thru axle, there are a few ways to check. First, take a look at the wheels. If they look like they’re attached with bolts that go through the center of the wheel, then it’s likely that your bike has a thru axle.

Another way to tell is by looking at the forks. If the forks have dropouts (the slots where the wheel attaches) that are wider than usual, then it’s likely that your bike has a thru axle. Finally, you can always consult your bike’s owner’s manual to be sure.

Thru axles are becoming increasingly common on bicycles, so if you’re in doubt, it’s always best to check!


Mountain biking is a great way to get exercise and enjoy the outdoors, but it’s important to know a little bit about your bike before you hit the trail. In this blog post, we’ll take a look at mountain bike axels, common types of problems that can occur, and how to fix them. One of the most important parts of your mountain bike is the axle.

The axle connects the wheel to the frame and allows the wheel to rotate. There are two types of mountain bike axles: quick release and thru-axle. Quick release axles are easier to remove and replace, but they’re not as secure as thru-axles.

Thru-axles are more difficult to remove and replace, but they offer a more secure connection between the wheel and frame. If you’re having problems with your mountain bike axle, there are a few things you can do to fix it. First, check to see if the axle is loose.

If it is, tighten it up with a wrench or Allen key. Next, check for damage on the threads or in the hub itself. If there’s damage, you may need to replace the axle or hub.

Finally, make sure that the QR skewer or thru-bolt is properly tightened before riding again. Mountain biking can be a lot of fun, but it’s important to know how to maintain your bike so that you can keep riding safely for years to come!
