@wlukewindsor I’m stuck with qr as well, but I use those expensive DT Swiss things which you can tighten very hard. I doubt that’s the reason of clicking. Up to this point I’ve been running 2 bb spacers on non-drive side of the bb to improve the chain line… (it’s boost 12 speed drivetrain on non boost 135 rear hub frame…😂). Now I have proper spacers setup but the chain might drop a few gears from the top on backpedal…😩🙈
