• I've got SRAM Red 11 group on a bike I bought used. Now I want to fit 4 bolt cranks. Do I need chainrings compatible with Shimano road 11 speed? What's the thickness of the teeth? I don't know what the chain is but it shifts well so I assume it's 11 speed.

    Y tho?
    Don't worry about the thickness of the teeth, buy 11 speed rings and they'll be fine.

  • Because I happened upon a cheap scratched THM Clavicula on ebay. It came with new carbon rings, still in their packets. Haven't decided whether to fit them for a giggle or sell them. I haven't measured their thickness yet, but I imagine they'll wear even faster than normal with a too-wide chain?
