1x (“One-By”) Drivetrain
There’s a revolution in drivetrains across the industry. Thanks to the recent introduction of hyper-wide cassettes from SRAM and Shimano, it’s possible to achieve massive gear ranges with only one chainring up front. That makes 1x an ideal configuration for folding bikes, because it reduces maintenance, weight, and complexity. Enjoy all the range of a 20-speed drivetrain, with none of the complications.
