I did not measure the chain as I put it in a zip lock baggie and sprayed it down with oil. I will have to pull it out tho before I order one.
You were correct, Dibe. If the front sprocket remains the same, and the rear sprocket increases 10 teeth in size, you will need a drive chain 6 links longer. Since the chain only contacts half the teeth on a given sprocket, increasing the rear sprocket by 10 teeth would require the drive chain to be 5 links longer. However, drive chains should have an even number of links. Therefore, increasing the rear sprocket by 10 teeth requires a drive chain which is 6 links longer.
