Looks good. Did you do any mods to get the chainring compatible with the hidden bolt cranks?

Actually, the Q rings work great with the newer Sram crank and no mods were necessary to fit it. When I ran a Sram Force BB30 crank I had to do a small modification there because of the more beefy arm. You can see the details of that mod on the first page. FYI I'm still using that modded ring on another bike that I race and they have been performing fine with no failure. Shifting is spot on too.
