Frequently asked questions about tuning the Shimano 20 Metanium

Which spool bearings fit the Shimano 20 Metanium?
The Shimano 20 Metanium uses spool bearings in 5x11x4 and 3x10x4 (inner × outer × width in mm). You'll find matching tuning spool bearings in exactly this size on this page under the tuning parts. To swap them on this reel you need a Pin Remover, because the bearings are secured to the shaft with pins.
Which bearing class do we recommend for the 20 Metanium?
For the Shimano 20 Metanium we recommend APEX, our highest tuning level. It gets the maximum casting distance and smoothness out of the reel and is especially worth it if you cast light lures or want every last bit of performance. The recommendation is based on how this reel is typically used.
Which handle and knobs fit the 20 Metanium?
The handle fitting of the Shimano 20 Metanium is 7x4 (wrench size × shaft diameter in mm). Every tuning handle with a 7x4 fitting fits directly. Tuning knobs in the sizes shown on this page fit the stock handle and our tuning handles.
Do I need special tools to change the bearings on the 20 Metanium?
Yes. On the Shimano 20 Metanium the spool bearings are secured to the spool shaft with pins. A Pin Remover lets you pull the pins out cleanly without bending the shaft. Apart from that you only need a suitable screwdriver for the side plate.
Can you install the tuning on my 20 Metanium?
Yes. Send us your Shimano 20 Metanium, we'll install the tuning parts professionally, clean and oil the reel and send it back ready to fish. You'll find the tuning service via the button above.
