• Product description

  • Bearings are a very small part of your bike, but play one of the biggest roles in terms of its performance. The life expectany of a bicycle component is highly correlated with the life-time of the bearing, which is used in the product. The balls of ceramic ball bearings have a greater hardness than steel balls. This results in a longer lifetime of the bearing. Furthermore, ceramic balls have a smoother surface than steel balls. This results in less friction when the bearing is spinning.
  • The black surface treatment on the Yuniper NITRO-bearings makes them less prone to rust. Improved seales reduce the probability of water and humidity getting into the bearing. Furthermore, we used a high end grease which protects the inner structure of the bearing and assures a very good lubrication. Internal clearances and accuracy classes are no foreign words to us.
    • Please inform us, if you wish your components to be equipped with our black Yuniper NITRO-Ceramic bearings.
    • Our standard bearing sizes are listed here. If you are looking for other bearing dimensions, please appoint the requested dimensions to us.
