How do I know what crankset I need?

Cranks come in a range of sizes, most commonly from 165mm to 190mm, and ideal crank length is often determined by three factors: your height, your cycling discipline and your personal preferences. If you change your crank length, it will change how it feels to pedal your bike, and it may change your fit on your bike.

How important is a crankset?

Cranks are one of the most important parts of your bike, allowing you to convert the power produced by your legs into rotational motion that drives the bicycle forward. Cranks come in a range of lengths, like handlebars and saddles, so knowing what crank length is right for you can be a bit of a minefield.

What difference does a crankset make?
