Are 10 Speed and 9 Speed chain pin the same?
 

My Shimano 10 speed chain that I ebayed is missing a pin. I was wondering if I can use a pin for my Shimano 9 speed chain?

Thanks for reponses.

Buy set of a Shimano replacement pins at your local bike shop. And buy the 10-speed variety.

Honestly, why did you buy a chain online? Did you even save anything after shipping costs? Obviously the chain is used since new chains come with pins. Do you have any idea how worn it is? Plan to find out?

No, the pins are not interchangable.
