Hi 004dam, I have upgraded the following bearings on the certate, which will fit the Bradia and Luvias:
Spool Bearing
2 x Handle Bearings
Line Roller bearing
The Certate comes with a line roller bearing, however this bearing is always prone to failure. Because the line roller directs wets line onto the spool (especially salt water) then you are getting a small amount in the bearing easch time you fish. It makes for a fast failure. I oil etc each time - still happens. The plastic bushing does a good job here and wont corrode.
