New, never used. 39x130mm.
Carbon, with double spacer kit and double Garmin/Wahoo/Bryton mount kit. + double headset caps. I have a double kit for everything (spacers, caps, mounts).

Made in China.
Price is non-negotiable, as I paid more than what I am asking.
I am selling it because I can no longer use such extreme measurements. I use a classic 42x12.

New, never used, never tested! It can be mounted on many bikes quickly, because the cables run externally and can be hidden by the bar tape.
