Frequently Asked Questions (FAQs)
1. How do I know what crankset fits my bike?
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.
2. How do I know what size crankset I need?
Crank length is measured from the centre of the bottom bracket axle to the centre of the pedal axle. If you're not sure what length the cranks on your bike are, the quickest way of finding out is typically to just look at the backside of your cranks, just below the pedal axle.
3. Why do Ebikes have short cranks?
Shorter cranks will add some valuable millimetres of ground clearance and might prevent you from crashing or being thrown off the saddle.
4. Are bike cranksets interchangeable?
Cranksets are not always interchangeable. Every crank is designed to work with a specific bottom bracket. Even if the cranks use the same interface (octalink, square taper, or hollow tech), switching them between bike brands or even models of the same brand is hard.
