I picked up a Sram pc1090r 10 speed chain at the Seattle swap meet yesterday. It was in an 8 speed box and I didn't check, $5 can't go wrong, right? I don't have any 10 speed rides so it's either toss it in the parts bin or cut it short and put it on the FG. Is it going to be too weak to use? It's light and shiny and would look good with it's hollow pins/plates and all but...
