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.

But if you are taking a downhill ride, a more extended variant will be the best option.

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.

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.
