All of the NJS brands (SG75, Dura Ace) only go up 54, as that's the biggest NJS allowed chainrings.

• Sugino makes the Zen line, but they're expensive.
• Gebhardt make them and they're not too pricey.
• Gr8 Designs does those custom orders from Oz.
• Dixie flyer makes some, also I believe on a custom order basis.
• I think Bespoke Chainrings makes some big ones, but they're also very pricey.

I've seen some international rides on Kronos and Ridea chainrings, but I can't figure out how one actually orders them. Perhaps they're largely a euro-only thing. Team GB also rides often on these all-black, mildly patterned/milled chainrings that have no identifying logos.

Thanks
