Therefore Thun developed the Mammoth. This bottom bracket cartridge features four sealed ball bearings, which protect and support each other. According to Thun, the life span of the four bearing doubled from 35,000 to 70,000 km.

Even if one ball bearing should fail, the other three will remain in use. By adding additional grease on both sides the life span was even further increased, as it keeps away water, sand and dirt.
