    1x11 Boost drivetrain -- what's the right chainline, 49mm or 52mm?

    Hi,

    I'm building up a 1x11 drivetrain on a Boost enabled Yeti SB5.5c and was wondering what the right chainline is.

    According to OneUp, it's 52mm (https://goo.gl/TGJnD3) but according to Wolf Tooth, it's 49mm (https://goo.gl/nnK7KV). OneUp's non-Boost offering is 49mm so my instinct is to go with 52mm but I figured I'd ask those who might actually know the real answer.

    Thanks!

    How desperate must someone be to give up so early?

    Let me add the official press release pics (as found on various sites)

    52mm.

    Ok, how about a non boost 1x11?

    yep that's 49mm.
