10TGR ( RD21182 Pinion Gear)

Genuine Shimano Pinion Gear (part #10TGR) — the pinion gear meshes directly with the drive gear to transmit rotational force from the handle to the rotor assembly. Worn pinion gear teeth result in clicking, skipping, and loss of cranking power, especially under heavy drag pressure. Cross-references with Shimano part number RD21182. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
