As simple as a headset may be, the Volcano integrated headset comes w/ the integrated cone race system that allows self-adjusting steering compression w/ just one single cap, using the top cap for both functions. Available in three height options: 15mm height like the style Courage Adams & Devon Smillie ride, a 7mm medium height option, & a super low-profile option, for riders that dislike the look of spacers & want their bars a little lower like Sergio. The Volcano headset paired w/ Volcano stems and Volcano forks make for one perfect setup.
