8-speed chains are wider than 9-speed chains, which are in turn wider than 10-speed chains. I couldn't find any information about 11-speed chains. But I wonder if there is any evidence that the narrower a chain gets, the faster it wears, all other factors being equal. There will be less surface (load-bearing) area as the chain gets narrower, I would think. With higher loading, I would expect wear to occur at a greater rate. Is this reasonable?
