Press Fit bottom brackets

Pressfit bottom brackets provide a secure and efficient connection between the bike frame and the cranks. These bottom brackets are designed to be press-fit directly into the frame, eliminating the need for external cups. Among the advantages of pressfit type bottom brackets are better stiffness and easier maintenance. In addition, the pressfit construction helps reduce the overall weight of the bike by eliminating the need for additional components. When choosing a pressfit bottom bracket, it is important to consider the specific requirements of the frame. Different bike manufacturers use different standards, for example BB86, BB92, BB30 or PF30. To ensure compatibility and optimal performance, it is essential to select a bottom bracket that matches the specific frame standard. In the MTBIKER shop, we offer a wide range of pressfit bottom brackets, which are designed to meet different frame standards and provide a reliable and durable solution for your bike.
