Drivetrain tooth capacity for SRAM RED eTap AXS 36T Max rear derailleurs is 39T. (Drivetrain capacity is the amount of slack chain a derailleur is designed to manage, based on the number of teeth in the drivetrain. Drivetrain tooth capacity is calculated using the following formula: [difference between tooth numbers on smallest and largest chainring] + [difference between tooth numbers on smallest and largest cog on cassette]).
