    American Classic Smokin Gun Boost offset?

    Iíve just bought a set of these in 29er boost flavour but am struggling to figure out if I will need an offset chainring.

    I know that most boost designs seems to push the hub flange outwards, but the ACís appear to keep as per normal and space out on the non drive side. Therefore Iím a little confused as to whether it will need the offset chainring or not.

    Any ideas? Thanks

    The difference is minuscule. Probably both will work. Personally I'd prefer to use a non-boost setup to keep my chainline biased to the friendly gears I use the most.

    ^^^ +1. If you have clearance between the ring and chainstay, non-boost offset works best, IMO.
    Do the math.
