Description
Switched to the 2-speed wheel and removed the e-shifter?
Get rid of the error 44 by mounting this simulator. It bolts straight to the mount of the original e-shifter using the original screw and plugs into the bike. It covers the hole in the frame with the housing. It simulates a real e-shifter, so the bike does not know the shifter is removed!
Compatible with the X3 and S3
