Why Choose 4mm Inward Offset?
When converting a road crankset from 2x to 1x, the chainline may become too far outward if a standard chainring position is used.
The 4mm inward offset moves the chainring closer to the center of the bike, helping to:
- Improve chainline alignment
- Reduce drivetrain noise
- Improve shifting smoothness across the cassette
- Provide better compatibility for 1x road setups
