My wife's bike is an old Marin Muirwoods and the Shimano STI front shifter has broken.
It is a 3x7 21 speed and the derailleur seems to work fine but the shifter just won't pull the cable. The shifters are separate from the brake and have two push levers to change up and down.
Does anyone know if I were to replace the shifters with a Shimano Tourney 7 Speed Mountain Bike Revoshifter SLRS41-7 (a twist gripshifter) whether it would be compatible with the Shimano 200GS front and rear mechs?
Thanks in anticipation of your wisdom !
