Boa Black Belly Steel Bearings – High-precision, budget-friendly bearings with inbuilt spacers and speedrings.

Our Boa Blackbelly Steel Bearings are made to the same high precision tolerance as our Blackbelly Ceramic Bearings but are designed to be easy on the budget. They feature inbuilt spacers and speedrings that prevent the shields from being crushed from overtightening. They are also filled with our industrial nano-ceramic grease, which helps to polish the steel balls over time and keep them performing at their optimum.

These bearings are based on our years of experience making high-quality bearings and have been tested by thousands of riders worldwide. They come packaged in a nice metal tin with a foam insert to keep the bearings nice and secure.
