Pressing a button that is assigned to gear up on my pro-race results in the gears going up twice i.e from 1 it will goto 3 and 3 to 5. Is this normal behaviour? as i was thinking of wiring in a frex style sequential shifter straight onto the pro-race button adapter using micro switches.
Or would i need to purchase somthing like a JC24 Joystick Controller to achive this?
Regards.
