1x vs. 2x drivetrains might be one of the most contentious topics in gravel cycling. In the last 3 years, more riders have won Unbound Gravel using a 2x drivetrain, but diehards like Bruce still believe in the simplicity of a 1x. Bruce explains the pros and cons, why he’s ditched the front derailleur for racing, why he prefers smaller chainrings, and why he’s also become a fan of electronic drivetrains like SRAM AXS.
