• Quarq PMs. I have a SRAM 11 speed chainset with 8-bolt spider interface. I'm looking at getting a Quarq spider. What compatibility issues do I need to be aware of (apart from BCD)? Can I buy a spider even if it's labelled AXS or DUB, as long as it's got an 8-bolt fitting?

  • I’d be careful, some of the DUB stuff isn’t compatible.
    I ordered a SRAM AXS spider to go on my DUB AXS Chainset and guess what, I need the direct mount version.
