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

Made in China.
Price not 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.

The price does not include the double parts.
