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

Compatibility

This chainring set is compatible with the following Shimano road cranksets:

Also compatible with:

• 110 BCD Shimano 4-arm power meter spiders
• STONE 110 BCD 4-arm spiders
