Since getting 11 speed, got in a routine of being regimented with the chain cleaning, it’s either degreaser in a muc-off chain cleaner if i’m doing a quicker washer or chain off and into a jar of white spirit overnight when i’m giving it a full clean, followed by water rinse and dry on low oven.
Got 1500 miles, that’s 3 chains, one cassette, cassette is now worn. Chain was replaced before 0.75 each time. I have no idea if that’s good or bad though.
It has faired no better than a rinse under the hose.
I’m sort of with mike on this one, you may get the chain surgically clean, but 10 mins later, dry (dust) or wet, it’ll wear in the same way anyway.
Just need to keep on top of the gunk/grit build up i reckon.
