I am looking at replacement chains and would like to get feedback from those who have experience/knowledge about various grades and brands of chains. My question: SRAM has 5 choices in their 9-speed chains; unplated, nickel-plated outer links, nickel-plated outer and inner links, cross-link (whatever THAT is), and hollow-pin. Where is the value/durability point? The parts person at a LBS said that nickel plating made them shift better and that since only the outer links were involved with shifting, the one with nickel-plated outer links was the best choice. If you keep your chain clean and lubed does it make sense to pay more for a plated chain?
