From experience I expect 800 kms from a 1 x 10 chain on wide range cassette, compared to 2500 kms from a 2 x 10 speed chain. Think its the wide chainline swings and increased tension in bigger rear cogs that kills the chain. I run my Sherpa 2 x 10 for this reason. I still like 1 x on my Turner Sultan though and accept the chain wear
