Propelling BB 30

Fun 5º bearing technology uses a patented 5º angled bearing structure. Its specially angled interface guides the bearing into position more smoothly, helping center the crank spindle for smoother pedaling and efficient power transfer. Because the bearing seats more naturally, it reduces the installation force normally required when mechanics press conventional press fit bearings into place, allowing easier hand installation and removal. By directing pedaling force and side loads through an angled contact path, the design also improves stability, smooth rotation, and long-term durability.

This ceramic ball bearing system uses ceramic balls made from an extremely hard material that resists wear, corrosion, and shape change during riding. Their smooth rolling contact helps reduce resistance for faster, more efficient rotation. Combined with AWAKE grease, the system also gains strong protection against water, mud, and corrosion, helping maintain lasting smoothness in rough terrain, wet weather, and demanding riding conditions.
