Criteria Used for Evaluation

Materials

What you want to focus on here is the design of the crank arms. In specific, what materials have been used to make them.

Alright, so your first order of business is to assess the design of the crank arms (one of the significant components of MTB cranksets). Back in the day, steel crank arms were commonly used. But, as you probably noticed while looking through this list, most of the modern models will be made with either aluminum or carbon fiber crank arms.

The question is, though, which material is better when it comes to the crank arms? Well, just for the record, neither aluminum nor carbon fiber is bad choices. But, let’s start with aluminum. Typically, you will find aluminum crank arms on low-to-mid-range cranksets. Aluminum crank arms are not only light in nature but also stiff and sport a certain level of toughness.

Then again, most top-end units will be equipped with carbon fiber crank arms. If you want premium, then carbon fiber is the way to go. However, this will come at a price that some of you will not be willing to pay, and that is fair.

Either way, the sheer tensile strength advantage that carbon fiber has over aluminum (over 11 times) is impressive. But, it also manages to be lighter than aluminum by quite a large margin (which is remarkable). Oh yeah, and the stiffness provided by carbon fiber crank arms is second to none.

Size

The material of the crank arms is important but so is the size. Of course, you also can't overlook the chain ring setup that you prefer.

To continue talking about crank arms, there is also something else you need to assess, and that is their length. This is important as not all MTB cranksets will come with the same sized crank arms. They can range anywhere from 165 to 180 millimeters. However, most commonly, you will see them measure 175 millimeters in length.

But why should you care about this anyway? Well, depending on the size of your legs, you may want shorter or longer crank arms than other users. Again, 175 millimeters can be considered the norm. To gain a clearer perspective, it is recommended to conduct some research to see which length is recommended for your legs.

Now, let’s shift the focus to chainrings for a little bit. These allow the chain to drive the rear wheel. But, what you need to know is there will be options for single, double, and even triple chainring setups. For the most part, all are good.

Single chainring setups are made to simplify your drivetrain and can often be seen as more reliable. Double chainring configurations are probably the most popular and can account quite nicely for steep climbs and downhill rides. As for triple chainring setups, this may only be necessary if you enjoy riding on fast surfaces.

Effectiveness

The crankset is simply another component that can positively affect the performance of your bike.

Above all else, you probably are interested in buying MTB cranksets that can perform the way you want them to. They are one of the many components that can affect the experience of your ride. Of course, buying them all starts with the type of riding you will be partaking in.

If you enjoy cross-country racing then you will probably want a lighter rig with a wide range of gears. On the other hand, you may need more strength if you are into more “gravity” riding. This is where the addition of carbon fiber arms can be so beneficial for some of you.

Now, speaking of carbon fiber, it is worth noting that most hollow axle chainsets will be plenty stiff regardless if they sport carbon fiber or aluminum arms. For the record, with cranksets that place an emphasis on stiffness, you will notice an increased response in your handling.

Oh, and one last thing, also look for models that allow for really good shifting performance. The design of the chainrings can help with this, as well as specific proprietary technologies, as the smoother the gears shift, the better.

Compatibility

Above all else, do ensure that the crankset you buy (more specifically the bottom bracket) will work with your bike frame.

Alright, it is now time to talk about the last major component that makes up a crankset. This is referring to a bottom bracket but what exactly is it. Sometimes shortened to just BB, you can consider this the engine room of the entire unit. It consists of an axle that will be rotating inside all the bearings.

Now, some sellers will include a bottom bracket with their cranksets and others will notify you of which types are compatible. And, yes, bottom brackets themselves can provide different performance benefits and durability. Regarding the latter, look for the bearings to be sealed and protected from the elements.

Of course, you also need to ensure that the bottom bracket (either provided or paid for separately) will actually fit on your bike frame. The reason for this is bike frames can have differing bottom brackets that they will accept. This is not an issue that you want to run into, after all.

Additionally, pay attention to the speeds that the chainrings will accept. You probably do not want a single-speed crankset. But, you also need to know that the chainrings will only work with chains of the same speed. If you want several different speeds, look for MTB cranksets that are compatible with 9, 10, or even 11 speeds.

Weight

Yep, though it has been hinted at previously, this section directly addresses weight.

It seems to have been beaten to death already so we will not spend too much time talking about carbon fiber here. But, this section is one of the reasons why the material is so beloved by many mountain bike racers. While aluminum is known for being a lightweight metal (which it is), it only can’t contend with the lightweight nature of carbon fiber.

Now, with that out of the way, it is worth noting that weight savings can be beneficial for whatever riding that you will be doing. Again, though, do not mistake lightweight MTB cranksets for low-performance models. Remember, carbon fiber is also much stronger and stiff than aluminum.

Outside of weight savings playing a role in the portability of a bike, it can also be incredibly beneficial for racers. Mountain bike racers will not want to be bogged down with heavy bike components. And, the same concept applies to the crankset. Keeping it as light as possible will be very important to some of you.
