10BRB (BNT1697  Spool Tension Spring)

Genuine Shimano Spool Tension Spring (part #10BRB, BNT1697) — this spring applies pressure against the spool shaft through the cast control knob, allowing you to fine-tune spool tension and minimize backlash during casting. If the spring loses its tension, becomes bent, or breaks, the cast control knob will have no effect, leaving you unable to regulate spool speed and resulting in frequent bird's nests. Cross-references with Shimano part numbers 10BRB and BNT1697. OEM replacement ensures perfect fit and factory performance.
