Element-Exclusive durable headset system :

• •  Oversize machined headtube
• •  Oversize Large-Ball 36˚ ACB bearings (36-OS)
• •  Stronger and more durable than other intergrated systems.
•  

The superior 36º Oversize standard is used in the Krypton-36 and Fusion headsets.

The table and photos below compare the 36º OS standard with IS and ZS systems.

• •  The 36º OS standard uses a larger angular contact bearing     (ACB) with signifcantly larger Ø5/32" (Ø4mm) balls inside, more durable than the Ø1/8" balls common in the other systems.

• •  Compared to the 45º IS, the 36º OS ACB sits on larger diameter 36º taper inside the headtube which has a much larger contact area with the head tube which better resists wear and damage.

• •  Compared to the ZS internal, the 36º OS ACB requires no tools to install in the frame. Because the 36º Oversize ACB is not press-fit like ZS headsets, the head tube cannot be ovalized by the cups.

• •  Compared to the ZS internal, the 36º OS ACB can use a larger ball-size in the bearing because the bearing does not need to fit inside a cup.
