Which chainring offset?

[duanelr]

Hi all, looking at upgrading my 2018 scott spark 940 chainring from the standard 32t x-sync2 sram chainring to a 34t.

 

Looking at the csixx chainrings, they come in 0,3 and 6mm offsets.

 

Which one is right for my bike?

 

1x12 sram gx,

 

Thanks

I use a 6mm offset.

2018 940 is a boost bike so use a 3mm offset chainring

Indeed a boost hub / frame yes, okay so 3mm. Thanks

Does anyone know if the BB & crank is changed on a Spark 940/2018, to a DUB BB & crank, will the chainring offset still be 3mm or is there something different about the dubb - maybe then 6mm.

boost chain line has nothing to do with the bb axle diameter.

it still uses a 3mm offset chain ring
