What’s in a MTB Crankset?
A crankset refers to the component of your bicycle drivetrain tasked with converting the reciprocating motion of your legs into rotational motion that drives the chain which the drives the rear wheel.
In simpler words, a crankset acts as a primary interface between you and your bike.
A typical crankset comprises of the drive assembly- which then includes the spider, crank arm, chainrings, and non-drive side crank arm.
Most of the modern chainset you’ll find on the market today come with an aluminum or steel axle- known as spindle- affixed to the drive side assembly. This axle is usually inserted via the bottom bracket frame shell. And the non-drive side crank arm is then attached to it using a fixing bolt.
For your info, the bottom bracket acts as the engine room of a crankset and consists of an axle that rotates inside sets of bearings.
As for the older models, they do not come with the integrated axle spindle. Instead, they feature a socket for the two bottom bracket ends to insert.
Keep in mind that cranksets come in a wide variety, which explains why it’s always important to pay close attention when shopping to ensure you get the best mountain bike crank set.

MTB Crankset Buying Guide For Beginners
With all the different types (thousands of thousands actually) of mountain bike cranksets available on the market today, getting the right model can become confusing for beginners.
In this section, we’ll share with you the selection method we promised you at the beginning of this post. This will help you make a wise decision when buying your bike’s chainset.
Here’s how to pick a crankset for your MTB:
Choose the right crank arm length
The first step to finding a crankset for your MTB involves checking the crank arm length.
The standard length for the mountain bikes is 175mm. However, the smaller frames, as well as the women-specific frames tend to come with a slightly shorter length of around 165mm.
In general, the length ranges from 165 to 180mm. While the shorter arms are great for uphill, the longer ones work great for downhill.
When selecting crank arm length, you should factor in your leg length. Longer Mountain bike crank arm lengths are ideal for longer legs, and shorter cranks are suitable for shorter legs.
If you’re not sure what length will work for you, you can resort to the trial and error method- by experimenting with different sizes until you get a comfortable length for you.
A crankset usually comprises of two main parts- the crank arms and chainrings- connected together. Each of these parts might be designed using different materials- like carbon fiber, chromoly steel, titanium, aluminum alloy, etc.
When buying a crankset, it’s important to check the material used to design them and compare them with your other bike components materials. For instance, if your bike has carbon fiber parts, you’d want to look for carbon cranks that are equally stiff and lightweight.
This also helps you maintain a unified look of your MTB.
If you prefer steel, then make sure its Chromoly steel as it’s more durable and reliable than other forms of steel.
If you have some bucks to spend, you can go for the titanium cranks.
Check the chainrings (and the gear ration)
The cranks gear ratio is also an important consideration as it directly determines how hard you’ll need to work to turn your bike wheel. The ratio is determined by comparing the number of front chainring teeth to the rear cog teeth number.
The higher gear (a bigger front chainring to small rear cog) requires more energy input but rewards you with more speed and power- making it suitable for downhill and flats.
Low gear (smaller front chainring to big rear cog) takes less energy to generate less power- making it suitable for hard ascents.
Before buying a crankset, be sure to check the number of chainrings it comes with and- as well as the available sizes- and compare them to the rear cog.
Bottom bracket style
Lastly, you should check the compatibility of your crankset with the bottom bracket (BB).
A crankset attaches to a bottom bracket bearing assembly which then fits insides the bottom bracket shell of a frame.
Each crank runs on its own BB design, so it’s essential that you match your new crankset to a compatible bottom bracket.
Here are more details on how to select the right bottom bracket that matches your cranks.
How To Take Care Of Your Crankset?
As you already know, a bike is a collection of various parts that work together to help you explore the world.
The crankset, in particular, comprises all the parts between your pedals and acts as your bike transmission- transferring your leg energy into pedals, the chain, and eventually the rear wheel.
That said, taking care of your crankset is a crucial exercise that will help it perform at its best at all times.
The process isn’t quite hard, and only requires you to do the following:
1. Start by cleaning your crankset thoroughly
The first and the most important thing you’ll need to do to take care of your bike is making sure it’s always clean and dry. Dirt and grime tend to easily build up the crankset- affecting the overall bike performance.
Given that most of the modern models come with sealed bearings, you don’t have to lubricate it. Just wash it after every use/cycling.
And when washing the bike, avoid spraying water directly to the bearing area. Additionally, never use a power sprayer.
For even better cleaning results, be sure to use a stiff brush (say a toothbrush) plus solvent.
Grab a screwdriver and wrap it with your cleaning rag or Q-tip to help you easily clean the hard to reach areas.
2. Regularly examine your chainset for any issues
Regular examination of your chainset involves the following steps…
i). Examine the crankset after every ride to ensure all its parts- including the chainrings and crankarms- are in decent physical condition. Be on the lookout for any dents, cracks, as well as other damage signs.
ii). Also, check the crankarms for play. Doing this is as simple as grabbing either arm and trying to rock it back and forth- perpendicularly to your frame. Pay attention to any movements that might suggest that the bearings require adjustments or are damaged. Also, confirm that crank bolts are loose.
iii). When pedaling your MTB, check if there’s any bending in your MTB crank arms or pedal. You’ll easily detect this during pedaling as it feels like back-and-forth motion or an up-down rocking motion.
Immediately you detect such movements;
Take off the pedal, hold it by the attaching to your crankarm and spin it (the pedal). If it doesn’t spin smoothly, it’s most likely broken down, and you’ll need to repair it. If it turns smoothly, however, then the crankarms might be the problem, and you’ll need to replace it.
What to do if you get any of the above conditions?
What you just need to is fix the problems on time, to prevent them from growing into serious issues. I’d recommend you to take your bike to a reliable, trusted local bike repair shop for professional repair.
