Performance Engineering

The oversized 18-tooth pulley increases chain wrap while reducing articulation angle, helping to lower drivetrain friction and improve transmission efficiency. Combined with precision ceramic bearings, the result is a smoother pedaling feel, quieter drivetrain, and more consistent shifting performance under load.

The narrow-wide tooth profile further improves chain stability, making it suitable for both high-power sprint efforts and rough road or gravel riding.
