After using my Caliper to measure ekar sprocket distance and cable pull distance I calculate the ekar pull ratio
each sprocket distance: 3.36mm
each cable pull distance: 2.48mm(Not too accurate, I may measure it again in the future)
Pull ratio for Campy Ekar ≈ 1.35
Not compatible with any other groupset.
(similar to sram 1.33? I am not sure)

Wow, do you have accurate data? I have searched a lot of information but they still lacks some groupset pull ratio
(https://www.mtb-news.de/forum/attachmen ... f.1415361/)
this is currently have the most complete information about pull ratio but still lacks some like cp ekar, cp new 11s+

The pull ratio for Campy Ekar is approximately 1.35, which is not compatible with any other groupset and is similar to SRAM's 1.33 pull ratio. However, due to the inaccuracy of the cable pull measurement, it is recommended to measure it again for more accuracy.
