Kind notice: We write choice name wrong, item is EC34/EC34, we have to change later due to promotion process now. Product Details Stylish, durable, and easily serviceable.  Those were the goals when designing our headsets.  We machine engrave our logos for a classy look, use durable and easily replaceable Enduro stainless steel angular contact bearings, and use a "split" crown race design that you can install and remove by hand. The EC34|EC34 style is often referred to simply as an “1-⅛” headset which, most of the time, is enough of a description to get you the correct headset.  But nowadays with all the different headset standards available we needed to get specific so check the SHIS specs below.  SHIS?  Yep, that's the "Standardized Headset Identification System" used to verify compatibility. Specs 6061-T6 aluminum Machine engraved logos Easily replaceable Enduro stainless steel angular contact bearings “Split” crown race for tool-free installation and removal Stack height Upper: 15mm Lower: 12mm What’s in the box One headset which includes: Top cap bolt Top cap Bearing cover Upper bearing compression ring Upper bearing Upper cup Lower cup Lower bearing Crown race Headsets no longer include Star Nuts due to the Earth’s star nut overpopulation crisis. Compatibility A perfect match to our really sweet matching headset spacers, available separately The EC34│EC34 headset is designed to fit frames with straight 34mm/34mm head tubes and straight 1-⅛” (28.6mm) fork steerers The “EC” stands for “External Cup” meaning the section of the cup that houses the bearing sits outside of the frame’s head tube and the “34” stands for the 34mm “skirt” that presses into the frame.
