    STEEL chainrings, where??

    Actually I'm gonna answer that for myself. NOWHERE!

    So basically I'm looking for a 42t in 5bolt 110bcd and a 42t in 4bolt 104bcd. And they have to be thicker than 9-10-11-12 or whatever speeds they are now running. I want the chainring to be perfect thickness for an 8sp chain. Also I'd like some long lasting material. 304/316 and such crap I don't want. Needs to be hardened steel.

    And nowhere can I find this!! I'm starting to get a little pissed off actually.

    Right now I'm running alu rings but I don't think they last very long. I get about 1 year (commuting). My old shimano 9sp steel chainring lasted a lot longer than that. But it had shift ramps. And I'm on a 1x6 (8sp stuff).

    So now I'm considering having a few chainrings made instead. By a machine shop.
    Thinking about using Hardox 500, Hardox 500 - Wear-resistant steel with extra-high toughness - SSAB
    Its about 500 brinell hardness and the yeild strength is around 1400MPa, its at least 3-4 times stronger than the best alu. And probably 100 times longer lasting.

    My plan is to just send a chainring out to the machine shop and say "here copy this in hardox 500", so now I need to know what chainrings are the best ones to copy, Thinking tooth profiles and such. This would be for a 1x6 or so.

    So which ones are good "references" to copy?

    Surly Stainless Steel Chainring > Components > Drivetrain > Chainrings | Jenson USA

    that will cover your 110bcd ring. it's meant for 7,8,9 spd chains too.

    the 104 42t will be harder to find... if it exists.

    If you're on Ebay, try to contact a seller that goes by 713_rogers713. I don't see any of his stuff listed right now, but he has in the past sold custom chainrings made from titanium and quality steel. They're not cheap, but they are worth it. I have a couple of his titanium chainrings and they pretty much last forever. The steel rings should last twice as long!

    I just measured my bolt circle on my triple DA cranks and they are 130mm, they looked quite large for 110.

    Regarding actiontec, at 200 a pop I'm quite sure I can have them made out of gold if want to. I'm guessing I will have to pony up a hundred or so a pop if I have them made out of quality steel.

    Yeah and and I also saw it was made out of 304 stainless, about as strong/long lasting as 6061 al.

    I also have one of his ti cogs and it is beautiful and lasts forever. You can also message him via FB. He usually responds within minutes. Search for "Labyrinth Metalworks". He seems to be doing a lot of custom knife work at the moment so I am sure he has a lot of steel sheets laying around
