whatever bike u got, look it up ont he internet and see what they are. 3 piece is when u can take off both crank arms and a 1 piece is when everything is connected together and to take it off u have to take off 1 side and bring it threw the crank area


someone else can explain it better tho

Simple.. there is a nut on the end of each arm.. and that connects the 3 pieces together

and the arm is usually a lot bigger compared to a 1 piece

i would look for a pic but im on a bad comp

this is pretty much what ALL one peice cranks look like...there is not really much design differences in the differening companies...so if you look on your bike and see this thing...like without bolts and everything just a solid peice then you have a one piece.



then if you have something like this...with bolts and everything...this would be a three piece crank set.

do you get it?

yes thats it right there and i explained in the other thing you posted but you should have shown him the other 3 piece cranks with pinch bolts that 3 piece up there is a 48 spline which holds the crank arms on tight and the spindle bolts keeps it on but then you got dual pinch bolt which has 2 bolts on the bottom of the arm that clamps the arm to the spindle then you got a single pinch bolt which which does the same thing as a dual but with 1 pinch bolt

3 piece is heavier and it falls apart more,
so it is junk and you should better buy a one piece























eeuh that was a joke
