STONE 130BCD 4mm Offset Narrow-Wide 1x Chainring for Shimano 5700/6700 & SRAM Red, 42T–60T
Convert a traditional 2x crankset into a clean, efficient 1x drivetrain with the Stone 130BCD narrow-wide single chainring. The narrow-wide tooth profile is designed to hold the chain securely without a front derailleur.
The 4mm inner offset improves chainline alignment when moving from a 2x system to a 1x setup, contributing to smoother running and better chain retention.
