Do you know what is the max thickness that XT 4p support?
I would like to try on my Rail 9.8 the BCA YOD4 disc: 203 is 2.15mm but 220 is 2.4...too much?
I'm very tempted too to upgrade to tech4 v4, but I hate to loose actual ergonomy with shiftlever and Oneup Dropper post remote that are attached directly to the xt brake; especially on the left, with 3 collars, one between brake, post remote or ugly bosch sx big controller would be too far
