We pioneered the 1x drivetrain, and the SRAM Force® 1 crankset evolves the innovation. It's lighter, stronger and simpler-non-aero chainrings can now be installed with a single tool. For cross, TT, tri and crits, this is the king of 1x.

THINGS TO REMEMBER

• Single-ring drivetrain simplifies functionality and reduces weight
• 48t variant has direct mount aero chainrings for better aerodynamics
• Non-aero chainrings can be installed with a single tool, making gearing changes a breeze
• SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control
• DUB™ bottom bracket adds durability and simplicity
• Can be upgraded to a power meter
