Headset GuidePerfect for measuring all internal and integrated bearings
Internal and Integrated headsets If you haven’t already noticed the internal and integrated headset age is well upon us. The variations in bearing ID, OD & angles can become quite confusing. We hope to make it easy for you to find out what headset or bearing you will need so that your purchase can be stress free.There are Three different forms of internal & integrated bearings;
Integrated:Without cups, this style uses bearings that fit directly into a specially machined headtube. This style, having first been introduced in Italy in the late 60’s is currently popular for both road bikes & BMX bikes. There are four integrated standards available in the market today.
There are four bearing styles utilised in an integrated headset;*TH system which uses 36/36 Degree ACB *Cane creek system which uses 36/45 Degree ACB *Campagnolo system which uses 45/45 Degree ACB*Insert ring system which uses 36/45 Degree ACBNote: FSA provide bearing sizes to suit all of the above
Internal:With cups, & sometimes called ZS or low profile system, this style of headset relies on cups that are pressed into the headtube. Once the cups are installed, bearings fit in the cups just like a conventional headset.
Intellaset:Intellaset is very similar to a conventional headset. Using the correct size headtube, this headset system offers the styling & look of an integrated headset but with thereliability & serviceability of a conventional headset.
Replacing bearings:When replacing bearings for integrated & internal headsets you can simply read the code off the side of the bearing. If the bearing is old & the writing is not ledgeable you may need a headset guide to help provide the details you need to purchase a replacement bearing.If you only have the frame and it does not have the bearings or cups you will need to contact the manufacturer or importer to find out exactly what type of headset will fit. Failing this you will need to use a headset guide.
Using micro spacers:Micro spacers are .25mm thick & fit between the compression ring and the top cover. Inte-grated headtubes are specificaly machined to accept proprietary bearings. Due to frame manufacturing tolerances, the vertical height of the bearing pocket can vary resulting in an imperfect fit between the top of the head tube & the headset top cover.
