●We manufacture and use Angular Contact Bearings (ACB) for our headsets. We use only the best manufacturing and quality control methods available.
●The manufacturing process begins with the rough shape of the bearing races being machined from high quality steel.
●Both the inside and outside of each race is then precision stone-ground to reach its final shape.

1. How many different types of bearings are used in the modern day headset?
Answer: There are at least 6 different kinds of bearings used in the bicycle headset. They include; radial bearings, thrust bearings and angular contact bearings. These three types of bearings all use ball bearings. The second category of bearings is the roller bearings which include the standard roller bearing and the tapered roller bearing. Both of these use cylindrical rollers.
