It just occurred to me that everybody riding a 1x mullet setup with his Gravel bike (and most probably does so with a SRAM over a Shimano GRX drivetrain) really opted for the worst of all the possible drivetrain efficiency downfalls: He not only suffers "cross chaining" efficiency losses in the outermost cogs of the cassette but also does so with the worst of all chains - the conventional Eagle AXS chain! Yikes! (see my previous posts to see why)
