trying to fix my wife's bike. front derrailleur can shift to the mid and big chainring, but instantly returns to the small chainring. so, the front derrailleur seems to be working. the shifter is a 7 speed grip-shifter.
cable seem ok as the derrailleur upshifts ok, it just does't stay there. i could replace the cable if that might be the problem.
the problem has to be in the grip shifter, right? like a broken spring in there?
thanks for any help.
