Cook Bros Threadless SS Headset (1 1/8")

It’s not all in your head...

A meal is only as good as its ingredients, & at the heart of the Cook Bros. Racing Stainless Headsets are two, super-smooth, 45×45, sealed bearings covered by a coating of titanium nitride & filled with stainless steel balls. The titanium coating delivers a low friction coefficient, increased corrosion resistance & smoother rolling surfaces. Stainless steel balls further increase corrosion resistance. Cruise longer & smoother. 

But there is more! Despite this being a threadless headset w/ cups, the 45x45 bearings also work in integrated headset applications. Toss the cups, pop the bearings in your new frame, and roll!

Key Standouts

• A split aluminum crown race makes installation and removal from forks super easy, allowing you to spend more time riding & less time fussing.
