Changing your front or rear sprocket can impact your speed substantially. When you replace your current front sprocket with a smaller one you will increase the low end torque acceleration, but decrease your top speed.  When you replace your current front sprocket with a larger one you will decrease the low end torque but increase the top speed. If you replace your current rear sprocket with one that is larger you will increase the low end torque acceleration but decrease your top speed.  If you replace your current rear sprocket with one that is smaller you will decrease the low end torque but increase the top speed.
