We use two top-quality bearing options when building our headsets: stainless steel for Premium Headsets, and black oxide-coated steel for Performance Headsets. Many of our headsets can be bought in either Premium or Performance, as the bearings are interchangeable. This photo shows a Zero Stack headset with both bearing options—stainless steel in green, and the black oxide in, well, black. What headset are you currently running on your bike? Let us know in the comments. #wolftoothcomponents #machinedinminnesota #bikeupgrade #headset #adventurebybike #red #lifeincolor #mtb #mountainbiking #builtbyhand
