This is new. On the Folding Bikes channel you've always pooh-poohed the simpler, lighter, less expensive 1X drivetrain by saying that it doesn't give you sufficient gearing range to pedal downhill. But now, you are apparently singing a different tune. To be clear, a 1x setup with a 11-46T cogset -- one that I've shown to work well in real practice both around town and on several extended overseas tours -- returns 418% gearing range, more than your stated target. So, which one is it? Time to come clean and stop flip-flopping. Does a 1x drivetrain with a 11-46T cogset provide sufficient or insufficient gearing range for you?
