Reds really are just the perfect bearing when you factor in the price. I’ve had plenty of sets that lasted a long time, and a few that lasted maybe 2 weeks. Sometimes you just get duds. Swiss are obviously better quality but they always made my setup sound dead whether it was the smoother and better quality balls and raceways, or a better quality stock bearing lube? I’m too lazy to clean bearings, so the dead sound and price never made them worth it to me. Reds for life.
