Introducing the brand new Boa Blackbelly Steel bearings. These bearings are made to the same high precision tolerance as the 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 filled with Boa's industrial nano-ceramic grease used in the Blackbelly Ceramic Bearings. The nano-ceramic grease will help to polish the steel balls over time and keep them performing at their optimum. These are based on their years of experience making high-quality bearings, tested by thousands of riders worldwide.
They come packaged with a nice metal tin and foam insert to keep the bearings nice and secure.
