It depends on your cassette, if it's a 9 speed run sram X7 or X9 and 9 speed grip shifter on the left, if 11speed (sram XD driver) run GX cassette, NX derialleur and grip shifter on the left. It is also possible to use a normal right side trigger shifter if you get a "slim" half twist throttle. Ebike.ca has them, we also have some.
