Do you wish you could get rid of a bunch of pesky component tangling? Or maybe you want a bit better aero for your race bike? Either way, Token has you covered with the S-Box (TK 1556SP). It gives you semi-integrated cable routing by setting up a system for your integrated headtube with access points for easy maintenance. Currently, the S-Box is only compatible with tapered 1.5" integrated frames and tapered 1-1/8" + 1.5" forks.
as title says, it's easy to install and it's the headset you would be using if you don't like or can't use an integrated handlebar with frames featuring headset cable routing.
