Criteria for Choosing the Best Crankset for Mountain Bike

Crank Arm Length

On regular-sized mountain bikes, the crank arm has a length of 175mm. However, smaller models come with crank arms of 165mm.

If you are one of the many that have been asking how do I know what crankset I need, here are excellent tips for you. Well, before choosing a suitable-sized crank arm for your bike, consider how you use your bike. If you spend more time uphill, you should select one with a shorter arm length. But if you are taking a downhill ride, a more extended variant will be the best option.

Also, think about the size of your legs. If you have short legs, you should choose a short crank arm. For people with longer legs, go for one with a longer arm length.

Apart from these tips, you can try out a crank arm of various sizes. But choose the option that feels comfortable.

But if you don’t want to spend hours finding the best crankset for mountain bikesthen consider seeking advice from a professional bike fitter. That way, you don’t get the wrong crank length.

Crankset Materials

A crankset has crank arms and chainrings. Usually, they are made from materials like titanium, aluminum alloy, carbon fiber, and various types of steel.

There are many bike crankset types, so before you choose any, consider the material. If you want something light but sturdy, choose a carbon fiber MTB crankset. But if you are on a low budget, go for aluminum or Chromoly steel crankset.

Chain Rings and Gear Ratio

Asides from the length of the crank arm, you should consider the gear ratio. This feature provides the energy needed to pedal your wheels. If you want to see the value of your gear ratio, you need to put the size of the front chainring and rear cog into consideration.

If you have a large front chainring but smaller rear cogs, your bike has a high gear. But if the rear cog is larger, then your bicycle has a low gearing.

High gear bikes are ideal for downhill rides or cycling across flat land because they offer incredible power and speed. However, they require a large amount of energy. For smooth uphill journeys, take a low geared bike because they produce less speed with less power. If you don’t know the best chainring size or crank arm length for your bike, then read on.

Consider the Number of Chain Rings

The earliest shifting bikes featured single front chainrings. But as time passed, companies manufactured bikes with double or triple chainrings. The cranksets with dual and triple traveled at greater lengths and moved faster than single – chained models.

But multiple chainrings have some drawbacks. First, they are expensive and weigh more than single models. Furthermore, they also have complicated features.

If you want the best crankset for mountain bike ridestry getting a model with single chainrings. But make sure the rear cog can withstand frequent ascents and descents on uneven ground.

If you love long-distance ride or climbing uphill, single chainrings cannot meet your needs. Instead, stick with cranksets that come with double or triple chainrings.

Bottom Bracket

When it comes to MTB crankset and bottom bracket compatibility, there are things you should consider. For one, different frames have different sizes of bottom brackets. Two distinct parts make up the bottom brackets- the bracket itself and the space (for the bracket) on the bicycle frame.

A compatible crankset should fit a bottom bracket without any hassles. But If you can’t get the right fit, you can purchase an adapter of the same brand as your crankset.

Some crankset comes with a bottom bracket, but if yours doesn’t, you can buy a new one or reuse the old bracket.
