Sram:
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
