Frequently asked questions about tuning the Shimano 23 Calcutta Conquest BFS

Which spool bearings fit the Shimano 23 Calcutta Conquest BFS?
The Shimano 23 Calcutta Conquest BFS uses spool bearings in 3x8x2.5 (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. To swap them on this reel you need a Pin Remover, because the bearings are secured to the shaft with pins.
Which handle and knobs fit the 23 Calcutta Conquest BFS?
The handle fitting of the Shimano 23 Calcutta Conquest BFS 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 23 Calcutta Conquest BFS?
Yes. On the Shimano 23 Calcutta Conquest BFS 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 23 Calcutta Conquest BFS?
Yes. Send us your Shimano 23 Calcutta Conquest BFS, 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.
