Designed specifically for our KAPZ - this carbon-steerer headset fork bung will sit neatly in your carbon forks and hold the bolt needed for your headset cap, securely & safely on your bicycle.

They will fit all 1 1/8" fork steerers and also any OVERSIZED (GIANT or Canyon for example) type 1 1/4" steerers too and will give you a thread for an M6 headset cap bolt!

will fit internal fork tubes from 22mm to 27mm - which is basically all 1 1/8" and 1 1/4" headset systems.

Fitting is a 8.2 second job and easy for any home-mechanic.

A great replacement if you wear your KAPZ slammed on your forks or if you currently have an FSA Integrated headset cap and want the freedom to install any KAPZ product you want.

Works with ALL KAPZ products and ESPECIALLY all boltless KAPZ.
