Super performance bearings for bait casting reels. Bearing balls are made of ceramics to remove weight. Outer and inner laces are made of stainless steel. 3 models are listed, Red BFS 1-10g, Red BFS 1-15g and Silver Regular bearings. Red BFS bearings are assembled with small bearings with red aluminum collar to remove weight from inner spinning part. Due to the small bearing installed, suitable casting weights are limited to 1-5g, 1-10g and 1-15g respectively. Silver Regular models are simple ceramic ball bearings without red housing, fine for less than 40g rigs.
