To make absolutely sure, just take your digital calipur, and measure across the sc pulley... Hell.. even go the lo tech route and a ruler will do it for you.

Tried to measure it with a tape while it is on the charger is difficult. The nut in the middle of the pulley makes it hard for an accurate measurement.
