NotSoBigBen Posted January 8, 2018 Posted January 8, 2018 Perfect chainline would be that your chainring is in line with the middle cog of the cassette, or slightly inboard of that.Besides with the eye is there a way to measure it? Still wonder how crucial it is ... Sent from my LG-D958 using Tapatalk

Sent from my LG-D958 using TapatalkThere is... but I am not sure how haha. I just know with a 2x10 crank you should offset it by 5mm to the inside to get it center. I would say pretty crucial if you don't wanna fork out on a new cassette every couple of months. Had a 0mm on my bike for a while when I should have had a 3mm offset thinking 3mm can't make much of a difference. I spent alot of time in my 42t cog and chewed through chains pretty fast, and that gear slipped quite a bit. Changed to a 3mm offset chainring and the problem was solved.
