Fully sealed bearings and custom made NBR seals to keep out dirt and water, offering a long lifespan in the worst conditions. An innovative retained compression ring and split crown race makes assembly easy.

HOW TO PICK THE CORRECT MODEL:
There are 2 parts to the headset the type and the length. T1-4 for example is Type1 (EC44/EC44) and length 4 (120-130mm)
1. Select the Type based on the internal diameter of your headtube and steerer type
2. Select the length of your headtube EXCLUDING ANY CUPS
3. Original cup type is not often possible, as usually ZS type change to EC type to give enough room to tilt the bearings.
4. Thats all!
Length 1 = 90-100mm
Length 2 = 100-110mm
Length 3 = 110-120mm
Length 4 = 120-130mm
Length 5 = 130-140mm
If your on the borderline between 2 sizes it doesnt matter which one you choose!
