10DX0  (RD20043  Pinion Gear)

Genuine Shimano pinion gear (part #RD20043, SKU 10DX0) — one of the two primary gears in your spinning reel's drivetrain that converts handle rotation into rotor spin. The pinion gear meshes directly with the drive gear and transfers power to the rotor assembly for line retrieval. A worn or chipped pinion gear causes grinding, skipping under load, or complete loss of retrieve. Cross-references with Shimano part number RD20043. OEM replacement ensures exact tooth profile and gear mesh for smooth, powerful cranking.
