Specifications

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
