Bontrager Carbon S-Bend Extensions. Not sure I ever mounted these, no signs of being clamped, so likely I didn't. Some scuffs & a nick in the clearcoat from being moved around a few times, but otherwise in great shape. Install them & put a bit of tape on 'em and they will be indistinguishable from being truly brand new.
Uncut, just under 375mm long. 175g on the kitchen scale. Located in Germany. 50â‚¬ + shipping Pictures here, https://ibb.co/hAweev & https://ibb.co/e4ubRa
