Proto Integrattron Headset
The Proto team's massive effort to create a light and tiny headset paid off, and Proto was able to produce this short nifty stack! The headset is integrated as much as possible, so for example the cap and wedge ring are combined to save space and weight of the product.
Due to the fact that the headset is short and integrated, the space around the fork will be more stable and the structure more resistant to bending.
Headset type: Integrated 1 1/8"
Compatible with: threadless forks
C-ring: aluminum
