Add some subtle bling to your bike with some bold blue pulleys. The ABEC hybrid ceramic bearings are smooth and long-lasting. The quality of the ABEC 5 bearings is Grade 3, one of the best. Grade 3 means that the ball is 3/1,000,000” tolerance of sphericity which means it is extremely round, which means less friction so that the Grade 3 balls rolls a lot smoother than others. The seals on these pulleys enable you to run these ultra smooth pulleys no matter the terrain or discipline.
