@Goodair, nice setup. I'm interested in your Dura Ace 1x setup. Building an electric folding bike and was going to setup with Shimano 105 5800 2x11 but since SRAM came out with 1x I was going to ditch the Shimano setup. Can you post a photo of the drivetrain or describe what you used to get the Dura Ace working. Would greatly appreciate it.
