A crank is basically the most functional part of a mountain bike. Without a crank, every bike is useless. It is attached to you via pedals, to the frame of the bike via the bottom bracket and to the rear sprocket and rear wheel via a chain. A crank can make or break a good cycling experience.

You must have run into many problems with your chain either going lose or breaking or just not functioning properly. A lot of it is due to a faulty crank. Hence, a crank is a crucial part of a smooth and satisfying bike riding experience. A smooth crank not only helps with the bike running smooth, but also allows better power to speed delivery.

Let’s take a look at some of the best cranks you can get for your mountain bike.

Best Mountain Bike Cranks Buyers Guide

What to look for when buying a mountain bike crank?

Quality: This comes down to the material used for the crank. Usually cranks use one or two materials in combination. The best combination is carbon and aluminium. Aluminum keeps the pedals stiff while carbon allows for a lightweight nature. 7000 series aluminium is a better option than 6000 series aluminium. Some cranks use steel which is plenty strong but not nearly as lightweight as aluminium or carbon.

Smoothness and Pedaling: This is a major aspect of MTB cranks. Smoothness depends on how well a crank can incorporate chainrings and gears. And pedaling is dependent on both chain and the crank itself. A good crank will allow for a satisfying pedaling which will convert more power into speed more effortlessly.

Price: This is an important aspect to consider. Many cranks offer great quality but ask for a hefty price as well. However, there are more inexpensive alternatives available as well that offer similar performance on a lower budget. If you want to take a look at them, this guide is perfect for you.


Can I put a road crankset on an MTB?
Keep in mind there is a difference in spindle length between a road and a mountain bike crankset. Road spindles are shorter than MTB spindles. Hence, it is better to have an MTB crank for your MTB.

Are shorter cranks better?
Shorter cranks can make you faster on a bike. Moving to a shorter crank can improve comfort as it reduces range of motion at the knee.

What is the best crank length for MTB?
Sizes in this regard depend on the bike length, but 175s are what is recommended for more leverage. 170mm crank arm length is the most commonly used.


Today we took a look at some of the best offerings for you when it comes to cranks for MTBs. Some offered great drivetrain compatibility while other used great materials for build like carbon. Chain gears were included with some of the offerings, not all. And same was the case with variety of color options.

You will adore whatever option you choose as we reviewed the best ones out there for you right here.
