I just bought a new Merax Finiss Aluminum 21 Speed 700C Road Bike and so far it is actually a great bike for the price but I would like to replace the following with speed shifters:
Front Derailleur: Shimano TZ-31
Rear Derailleur: Shimano RD-TZ50
Shifters: Shimano SA050
What I need to know is what would be good speed shifters to replace these with?
Any help in this would be greatly appreciated. I am a novice at this so please bare with me!!
