    Sourcing 5 Bolt (66mm?) rings
    Title says it all. Don't care too much about a proper 3 ring setup, but I have an old Alivio crankarm collecting dust, and want to know if there is anything available for a reasonable price, perhaps for SS use.

    Do you mean 110/74 or 94/58 perhaps?

    Nope, center to center, it measures about 40mm, and guestimating an approximate circle is about 66mm.

    It is literally 5 bolts (one circle). The original rings were all bolted through, with the individual rings shaped on (what I'm guessing was) an arbor press to match the profile of the crank and standard triple gearing (for a seven speed bike).

    The bike is came off was 12(?) years old, if it helps at all.

    Those parts are NLA, for a decade at least.

    "I'll Leave Yo (@ss on the side of the trail)" BCD was for a proprietary riveted steel triple chainring assembly. Nothing else fits it.

    Pity. It'll make a nice backscratcher, though.
