To fit carbon fork internal dimensions of 28.6 x 23mm

An absolute essential for any bike with a carbon steerer tube. A carbon Fork Bung is a 1 1/8 inch expander plug that tightens into the top of the steerer tube to give the headset top cap something to pull on when compressing the headset.

• Safe and reliable grip
• Use this instead of a star fangled nut on all 1 1/8 inch carbon forks
• Compatible with all our Road, T/T, Track and Cyclocross forks
