Best Answer

Through the use of chainrings - up front, and sprockets - at the rear with different sizes it's possible to change how much the rear wheel will turn WRT the pedals.

This allows you to trade strength for speed, or the other way around.

Moving the shifter lever moves a derailer which moves the chain from one sprocket to another which makes it either harder or easier to turn the pedals.

And the rider can keep pedalling at a comfortable pace and effort on the flat, up hills and down.

How do you work out sprocket sizes for bmx?

Divide your rear sprocket into your front sprocket. Like 25x9. 25 divided by 9 = 2.77. so 2.77 to 1 is the drive ratio. If you go with a smaller sprocket like a 24 in the front but still a 9 in the back, you are lowering the gear ratio to 2.66 to 1. So your bike will be slower but easier to pedal. If you go with a 25 in the front and a 10 in the back, you end up with a 2.5 to 1 ratio. Don't confuse gear ratio with gear inches, that's a calculation including the wheel and sometimes the circumference of the tire.

If you have different gear ratios in front than in back does it matter?

yes it dose matter you will blow your transfercase like i did.
