What is better 1 piece crank or 3 piece crank?
3 Piece Crank
As you might have guessed these are made of three pieces – 2 arms and spindle. The thread used to attach the arms is 9/16 inch. These are considered to be tougher and more durable than the 1 piece. In outdoor bikes a 1 piece crank is usually used for kids bikes and some lower end adult bikes.
Is a 2 piece crank better than a 3 piece?
In theory, 2 piece cranks should be stiffer because the spindle is integrated into one of the crank arms and thus the power transfer during pedaling is stronger.

How do bottom brackets work?

Upgrading your crankset typically means shedding grams, improving stiffness, and often getting much better craftsmanship and materials. Usually resulting in improved performance both under load and not under load.
How often should you change your crankset?
After 5,400 miles it is reasonable to replace the rear cassette and chain. The front chainrings may need replacing if they have been ridden with a wornout chain. The rest of the crank: the spindle cranks and spider should be fine. Sometimes it is cheaper to replace the whole crankset.
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.
