Different design compared to the OEM one:
re-engineered especially in order to work properly with Shimano 12 speed derailleur.
changes applied after a lot of complaints from riders,
after deep investigation, 8 prototypes, and more than one month of tests on 2 different bikes we have corrected the location and position of the derailleur according to Sram's and Shimano's specifications.
