    New question here. 22T ring installation - which side faces which?

    This is such a newbie question , but - with a "stepped/offset" 22T ring (pic below) - which side (stepped-in plane vs stepped-out plane) should I install it facing which way (drive side vs non-drive side)?




    By the way, is there a way to tell if a chainring is a alum or steel? I found another spare 22T, but can't remember which.

    Thanks for your info in advance,

    The 32t ring pictured would be installed with the counterbored side of the bolt holes facing the frame and the tab at the bottom of the pic installed in line with the crank arm.

    Does your granny ring have counterbored bolt holes? If so, that side faces the frame.

    The holes look exactly the same from either side, so I assume NO "counterbored". (What's "counterbored", anyway? You mean, like a lil' recess for the bolt's head?)

    This ring is just "stepped/offset" at the line in the pic (the line around the ring between holes & teeth), so the teeth plane/line is ever-so-slightly off-set from hole plane/line to one side (looking at it vertically).

    The one I have now is no brainer without any "stepped/offset" (completely a flat plane; the same from eithe side), but this one looks side-specific.

    Put a magnet on it. Al in non-magnetic.

    I would probably be inclined to put the side with the "22" stamped on it facing the frame. ie; if you took the crank off and the granny sproket was on top you could see the number.

    Look at the tops of the teeth. If the amount of angle (chamfer) cut on each side is different, mount it with the biggest chamfer towards the middle ring. This will give you the best chain pick up with the chain coming from the inner cassette cogs.

    If the teeth are chamfered equally on both sides, mount the ring so the stepped side faces you (away from the middle ring) as you bolt it on. This keeps the teeth closer to the middle ring, which is usually better. But if the chain brushes the middle ring when coming from the middle and outer cassette cogs, flip it over to improve clearance.

    The key to solving any problem is to understand and address the underlying cause.

    Nine times out of ten, the 22T stamp will be visible from the outside of the cranks.

    Welp.......

    Without knowing what chainring/crank/front shifter you're using, it's hard to be of help. You might just have to experiment with it.

    Just to clarify..., when you say the side with "bigger chamfer", do you mean the side that's "steeper (closer to 'vertical') in angle" (& longer surface), or the other-way-around?

    This is my XT crankset with rings attached. Clearly, the numbers on all three chainrings are stamped on the inside.

    I say install it and see what happens. If somethings doesn't seem right, flip it over and try again.
