Crank is that part of the bike that gets the least attention. Normally when a person purchases a BMX, he/she focus on the look, the handles, and pedals quality, among other things.
However, people forget that cranks determine the comfort level as they drive the entire BMX. Therefore, no matter how premium pedals you have or how beautiful the handle is, if the crank doesn’t have the right specification, all other features go to waste.
One reason for the lack of attention to the crank could be its technical reason that scares away the masses. However, the reality is that cranks are as easy to understand as the other parts of the bike.

Buying Guide of Best BMX Cranks
Similar to BMX Chains, the features of the BMX bike crank might seem a bit technical considering its parts and other features. Therefore, we have created this comprehensive guide to help you fully understand all aspects of the crank so that you can make an informed decision.
Different types of crank materials
A crank can be made from one of the five materials. They are regular steel, Chromoly Steel, Aluminum Alloy, Carbon Fibre, and Titanium. However, among all these materials, the Aluminum alloy is the most common of all.
The reason for the popularity of this material is that it provides strength and is a lightweight BMX crank.
3 piece crank vs. 1 piece crank
We discussed above how Aluminum is a common material used for a crank as it provides strength. Apart from the material, the type of crank also plays a role in how strong it will be.
For example, 3 pieces of cranks are stronger than 1 piece because they use good quality racing speed, bearings, and spindles, among other things. If you plan to use your bike on rough terrain, a 3 piece crank BMX will give you peace of mind.
Frequently Asked Questions

Does spindle diameter matter?
Yes, it does. It plays a crucial role in the performance of the BMX as well as comfort levels, so you should pay close attention to it.
A spindle typically starts from 19 mm and can go up to 24 mm. Large spindles are stiffer and lighter, making it easy to peddle. Smaller ones are a bit heavy but provide strength to the crank.
