The 40 tooth cassette cog would worry me. I checked Chain Reaction Cycles' website, and the Alivio is listed as supporting a max cog size of 34 teeth.
It worried me too. I was thinking that was with a front triple crankset, though, so it might fly with the single chainring. The worry for me was there not being enough room below the 40t cog.
I need to get more up to speed on 1x stuff.
