    If I want to replace the standard GX Eagle 32t Chainring on my Orbea Rallon (Boost Rear end) with another 32t GX Eagle Chainring do I need 3mm offset or 6mm offset?

    Can’t seem to find a clear answer anywhere….

    Does it not say on the chairing?

    Pretty sure 3mm is boost while 6mm is non-boost, but what onehundrethidiot says it should say on the GX chainring

    Yup, 3mm is boost, 6mm is non boost. (Pretty logical)

    Good shops usually list this info.

    3mm is boost, 6mm is non boost.

    I have a boost frame, but am running non boost wheels, but with a non-boost chainring to keep the chainline sensible.

    Cheers guys. I thought that my chainring didn’t have it on for some reason but after some scrubbing there it was in tiny writing – 3mm!

    Thanks
