By re-positioning the upper derailleur pulley closer to the small cassette cog and further away from the largest cog, we have been able to allow rear derailleurs designed to be used with 10-33T cassettes to be capable of running smoothly with 10-52T cassette.
Fully compatible with Sram 12-speed AXS flattop chain.
IMPORTANT: To be used in 1x setup only with the listed compatible rear derailleurs.
Compatibilitty:
SRAM 12sp RED AXS, SRAM 12sp FORCE AXS, 12sp Rival AXS, SRAM etap 11speed A2 rear mech, with 11/12-speed chains including Shimano HG+ and SRAM AXS flattop.
