So i thought i will put some info together and write it down in one place as i get more and more questions about correct chainline.
For all you guys who use most of the time a granny gears on the rear and say that middle ring position is still not ideal in terms of chain line, i have a different proposition.
A 64BCD chainring in 28T and 30T with xx1 tooth profiles. This makes your chainline of 44-45mm which means you will fill really comfortable on the granny gears with no rubbing, excessive wear and so on. This is in particular helpful when you use 2x crankset already. As we all know 2x cranks have much worse chain line than 3x ones. So 64BCD rings solve that issue.
So such solution is ideal for people on the 29ers or doing Enduro with 30T ring and 11-36T cassette.
for the ones who ask what to do with 104bcd tabs - you can mount a bash guard which will cover that gap. Then you gain protection and it will look like it was meant to be that way
almost like a complete crank from one manufacturer. 28-32 bash guard will be ready within 2 weeks.
Now, some of you don't know this trick so i will write it down again. To get ideal chainline you have to go for a ride and start noticing what rear cogs you use most. Ideally you should be using middle of the cassette for 60% of the time on your ride. If you are not then:
A- if you use granny cogs most:
change front ring for the smaller one. That way you will move to the middle of the cassette to gain same ratios you had before.
B- if you use small hard/small cogs most:
move to the bigger chainring. It will do same as above.
This is very simple and effective way of working your chainline if you can't touch your BB. This is a whole beauty about 1x drivetrains, but somehow most people don't recognize this method of alternating a chainline.
This is crucial to understand as it will significantly reduce chainring wear and will reduce grinding noises to minimum. It will also improve your efficiency and save cassette for longer

We also have a very limited run of blue chainrings right now (this needs to be ordered via email)
