Sealed retainer CrMo bearings

Sealed retainer CrMo bearings

The bearings of this headset are made with sealed retainer CrMo bearings. CrMo is a variant of steel that is mixed with chrome and molybdenum what gives the material strength. They are sealed to protect them against dirt, ensuring durability and easy replacement, making them a reliable choice for smoother rides. Although it is not as lightweight as aluminium it has a high tensile strength and is easy weldable. Therefore, it is stronger as standard steel and lasts longer.

Zero Stack (ZS) / Semi-Integrated headset

Zero Stack, or also known as 'Integral' or 'semi-integrated' means that the bearings are inside the frame tube as well, but the difference with Integrated is that Zero Stack type headsets have a separate cup between the bearing and the frame. This type of headset gives you the code ZS.
