Not long bought a Certate 2500R 10 and thought id do a bearing up grade in the spool and handle to make it 13 bearings,i found a kit on fleabay for 2 bearings for the spool to replace the bushes for just over $20 delivered and got the same size bearings 7X11x2.5 for spool and 4x7x2.5 for the handle from a RC store on fleabay for $13 for 4 spool bearing and 10 handle bearings,a very large difference in price for the same bearings,by doing this i now can up grade all my other reels with extra bearings and im sure the handle bearings will fit the line roller as well.
