A Headset Code is the collection of letters and numbers that describe a headset's relevant dimensions as well as how it fits into your frame. It's written as follows and describes all the info you need to know to identify a headset: ZS44/28.6 | ZS56/40.

Yes! Most Cane Creek headset parts are interchangeable and cross compatible accross the various model lines. For instance, the crown race from a Forty will fit in the same size 110 headset. The headsets must have the same headset code for parts to be cross compatible.

Yes! You can easily upgrade a Forty or Fifty to use the stainless steel Hellbender bearings from an HB70 or 110. All bearing sizes are lasered on the outside race for easy identification. If you have questions about fitment, please write to support@canecreek.com.

Sometimes. Many bike brands use standard bearing sizes and could benefit from an upgrade to Cane Creek bearings. However, some brands use proprietary bearing sizes that we do not produce. You can measure the outside diameter of the bearings in your bike to see if we make a comparable size. If you have questions about fitment, please write to support@canecreek.com.

All Cane Creek headsets are fully servicable and rebuildable at home. We sell replacement bearings individually if you need them, and they drop into the headset without the need for presses or special tools. Hellbender bearings in 110 headsets are guaranteed for life, and we will replace them if you have any issues for as long as you have the headset.
