DID's chains are among the best and wider one (525 enstead of a 520) will last longer if its cared for.

But if you want it to really last long be aware that even a riveted connection might be a weak point. So you might consider buying the chain as and endless one ( http://www.off-the-road.de calls it a closed chain). It is more trouble fitting it (have to disassemble more, but a good time to grease everything in the suspension and bearings)
