The KHE Bush Bottom Bracket offers a lightweight and durable alternative to the class sealed bearing BB through superior plastic bearing technology.
The KHE Bush Bottom Bracket is made of proprietary composite material that combines high performance polymers with precise additions of fibre reinforcements and solid lubricants. Because of its intrinsic advantages, plastic bush bearings have replaced metal bearings in thousands of applications from all industries, ranging from medical devices to food processing, marine equipment, pumps and valves or automotive applications.
** The bush bearing is not a rolling bearing, it is a friction bearing. This means there is more friction involved, the crank spin less than with regular rolling bearing BUT the coefficient of friction changes with the load. This means that when you start pedalling, the crank is a bit harder to turn, but when you ride, you do not feel any resistance anymore. In addition, when you are not pedalling, the pedals will not move by themselves as easy as with a rolling bearing. This means that on a no footer or tail whip variations, the pedals will stay in place.
