Bassnet hit the nail on the head. Abec 5's are a good upgrade but not really needed. I'll check to see if the new Chronarch 50 Mg spool fits but something tells me that it's a little different. It's a small reel that I like to use with 8# test so the stock drag is just fine.If you want to use the Calais handle then you will need to grind the handle shaft down to make it fit (Voids warranty) and then you need some other parts to go with it. If I were you I would degrease the spool shaft and the center of the pinion gear and make sure the spool raceways are clean as well as the out side edges of the spool.
