SPEEDLINE SEALED BEARING INTEGRATED HEADSET

1 1/8" Pro Headsets are Typically used on Expert XL, Expert XXL, and older style Pro Frames , or Any Frame that you wish to use a 1 1/8" Fork and Stem on.
1 1/8" - 1.5" Pro Tapered Headsets are Typically used on Pro size and Larger Frames with Tapered Head Tubes. They can be used with 1.5" or 1 1/8" forks and are used with 1 1/8" Stems.
We start with a high grade tool steel ACB ( Angular Contact Bearing ) sealed bearings with precision ground hardened steel balls. What does that mean to you? Probably not much, except that you know the bearings will last you a long time and they will spin nice and smooth.
Add on a nice CNC'd Aluminum top cap, a thin rubber dust seal to maintain the life of the bearings. The Bottom Aluminum race is split to allow ease of installation and removal.
The 1 1/8" - 1.5" Taper comes with 2 ( two ) bottom races to fit both the 1 1/8" Fork and the 1.5" Fork so you can use either fork.
