Hi Freddofrog,
Do you want to change just the PU chicken loop part or the whole quick release with chicken loop system ?
There is the question of compatibility across brands and products can change depending on the year/model of your bar.
Looking at the new Epic bars setup, I believe you could upgrade it with the newer Airush IQR system (new ISO standard compliant quick release)
Have a look at the video below. If you think it can fit, send me a PM and we can get you that spare part locally (
