How do you calculate sprocket rpm?
calculating sprocket RPM is very easy if you know what the RPM of the drive sprocket is. If you know that then it is a simple fraction problem. If you make the drive gear the numerator or the top part of the fraction and the driven gear the denominator or the bottom part of the fraction (DRIVE/DRIVEN) I.E. if the drive sprocket has 25 teeth and your driven sprocket has 100 teeth (25/100) that will reduce to (1/4) or a 4:1 ratio. So if your drive sprocket is spinning at 1000 RPM then your driven sprocket will be spinning at 250 RPM. You can plug your specific sprocket tooth count into that equation and come up with the right answer.
When I pedal my bike doesn't move The crankset just spins as I pedal How can i fix this to make it work 100 percent again?
You must have replaced a part. Either the Driver, Sprocket, or backrim. Your ratio isn't set right. with a 16 tooth driver you have to have a 32 tooth sprocket (i think. it might be 36) with a 9 tooth driver, you have to have a 25 tooth sprocket. i don't know how many spokes you need in your rim for either one though. go to a local bike shop and ask about it. sorry i couldn't help much. i havent messed with bikes in a while.
