    New question here. Chainline problem with 1x10

    Hi everyone,

    I'm having some kind of problem with my recently converted bike to 1x10, as the chainline is way off where it should be.

    I double checked that the bottom bracket spacer is well placed (2.5mm in the drive side for 73mm BB) and the chainring is attached correctly to the middle position in the old triple crankset i have (SLX M-670/675)
    I'm using a wide range 10speed 11-42 sunrace cassette and i'm getting the optimal chainline in the 7th cog, if i'm not wrong thats 2 cogs offset from optimal.

    It seems like i need 8-10mm chainring spacers....?? o.O
    Any ideas please
    Thx in advance
    Kind regards

    Refer to this post below for starters. I think switching to a N/W ring will get you to 47mm right off the bat which is close to ideal.

    Sorry but, arent those tabs to install at the outside of the crank's sipder instead of inside where i need them to move the chainring inwards?

    Yea, the tabs are for the outside and protect the arm junction. They also look cool.
