Product Information

Full details

The Shimano RD16822 spare spool is an essential accessory for anglers utilizing the Shimano ST-RA or ST-RB 10000 Baitrunner reels who need to adapt quickly to changing fishing environments. By keeping an extra spool on hand, you can instantly swap between different line weights, diameters, or braid configurations without needing to re-spool your primary reel on the bank. While this component is a genuine, high-quality replacement, it is strictly limited to the 10000-sized Baitrunner models and is not backward compatible with smaller or larger reel variants.

FAQs

Is this spool compatible with the 6000 or 8000 size Baitrunners?

No, this spool is specifically engineered for the 10000 size ST-RA and ST-RB reels and will not fit the dimensions of the 6000 or 8000 series.

Does the spare spool come with its own drag system?

Yes, the RD16822 is a complete spool assembly that includes the necessary internal drag components.

Can I use this for saltwater fishing?

While the materials are corrosion-resistant, always rinse the spool with freshwater after exposure to saltwater to maintain its performance.

Does this spool fit the newer Baitrunner D or CI4+ models?

No, this part is specific to the ST-RA/RB generation of Baitrunners and is not interchangeable with other Baitrunner models.

How do I know if I have the right reel model for this spool?

Check the underside of your reel foot or the box for the model number, which should explicitly state ST-RA 10000 or ST-RB 10000.

Troubleshooting

Spool feels tight or does not seat properly

Ensure the main shaft is clean of debris and the spool cap is correctly threaded before tightening.

Drag feels inconsistent after spool swap

Check that the drag washers inside the spool are properly seated and that the spool is clicked fully onto the main shaft.

Clicker sound is missing

Inspect the clicker pin on the reel body to ensure it is not bent and is making contact with the spool's internal gear.

Pros and Cons

Pros

Perfect factory fitment ensures no drag stutter
Allows for instant adaptation to different fishing conditions
High-quality construction matching original reel specs
Prevents the need to carry an entirely separate backup reel

Cons

Compatibility limited strictly to 10000 size ST-RA/RB models
Does not include additional line or reel components
Higher cost compared to generic aftermarket spools

Setup, Compatibility & Care

To install, ensure your current reel drag is backed off, unscrew the spool cap, and slide the original spool off the main shaft. Align the RD16822 spool with the shaft and secure it with the cap until it locks into place.

Compatibility Note: This item is designed exclusively for Shimano ST-RA and ST-RB 10000 Baitrunner reels. It is not compatible with smaller reels in the same range or other Shimano series.

Care Instructions:

After use in saltwater or harsh environments, remove the spool and wipe down the shaft with a soft, damp cloth.
Store in a cool, dry place away from direct sunlight.
Avoid using excessive lubricant on the spool clicker; a light coat of high-quality reel grease is sufficient.
