    58bcd rings / Alternative to whirly spider

    I've look and looked and searched all over, but I don't think the thing that I want exists. I want a 30-32t 58bcd ring. I know that for the majority of the cycling world that ring make zero sense, but I want to avoid using the spider for my mr whirly cranks while achieving a reasonable gear for my SS pug. I could do a 26t and smaller cog but I'd much prefer to run a larger ring and cog for longevity and efficiency. Ideally I'd like a 32/20.

    I thought about getting a solid steel cruiser ring for one-piece style cranks and drilling the appropriate hole pattern in it to make a ring. That would be the cheapest option that I have thought of, but a ready-made option would be easier because I'm lazy.

    I wanted to make my search known to the collective of fat-bike land. Surely I'm not the first to want to avoid the whirly spider.

    For all my bizarre custom chainring requirements, I go to Tomicogs

    He has made me rings for RotoR cranks (4 bolt 110bcd) and some other things. Very reasonable prices, I thought. Been a while, so I'll let him qoute.

    He says:
    "ChainRings!
    Yep, I'm also making chainrings now. 'Stock' sizes are 32t & 34t, in both 102(XTR) and 104 4 bolt patterns. Pricing is $40 each + shipping (~$5).

    Can also make custom rings, shoot me an email, we'll see what can be done."

    So far my mr whirly spider and wolf tooth chainring have been great. The problems I've heard of are from 5 bolt spiders.

    You know, I'd probably be fine with the spider. I might just look for a cheap one to pop up. I think I'd still rather avoid the spider.

    I also don't like the spider for 1x setups so I emailed surly about this last year. They didn't think that there would be enough demand to make them. Did you email Tomi? I'd buy.
