Fun5° Bearing Ultra 24 set

The Mortop Fun 5º Bearing Ultra 24 Set is a ceramic replacement bearing set for selected Mortop bottom brackets designed for 24 mm crank systems. BB Bearings are the rotating parts inside the bottom bracket that allow the crankset to spin smoothly when you pedal. Replacing worn bearings for bottom brackets can help restore efficient pedaling and extend the service life of your existing bottom bracket.

This bearing features ceramic bearing balls that help reduce rolling resistance, resist wear, and maintain smooth performance over time. Mortop’s patented Fun 5º design helps make bearing installation and replacement easier. Combined with AWAKE GREASE, the system also gains strong protection against water, dirt, and corrosion for reliable riding in demanding conditions.
