Fun5° Bearing 30 set

The Fun 5º Bearing 30 Set by Mortop is a replacement bottom bracket bearing set for selected Spinning, Propelling, and Screwing bottom brackets using 30 mm crank systems. Bearings are the rotating parts inside the bottom bracket that help the crankset spin smoothly when you pedal.

Featuring our patented Fun 5º tapered design, it helps make bearing replacement easier while reducing the risk of damaging the cups during service. This makes it a practical way to refresh smooth pedaling performance and extend the life of your existing bottom bracket. Combined with AWAKE GREASE, the bottom bracket bearing set also gains added protection against water, dirt, and corrosion for reliable everyday riding and long-term durability.
