Frequently asked questions about tuning the Shimano 17 Chronarch MGL

Which spool bearings fit the Shimano 17 Chronarch MGL?
The Shimano 17 Chronarch MGL uses spool bearings in 3x10x4 (both spool bearings the same size) (inner × outer × width in mm). You'll find matching tuning spool bearings in exactly this size on this page under the tuning parts.
Which bearing class do we recommend for the 17 Chronarch MGL?
For the Shimano 17 Chronarch MGL 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 17 Chronarch MGL?
The handle fitting of the Shimano 17 Chronarch MGL 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 17 Chronarch MGL?
No. On the Shimano 17 Chronarch MGL the spool bearings can be changed without a Pin Remover. A suitable screwdriver for the side plate is enough.
Can you install the tuning on my 17 Chronarch MGL?
Yes. Send us your Shimano 17 Chronarch MGL, 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.
