Gearing 14-Speed Shimano A070 STI Crankset Prowheel Ounce 42/52T Double Chainring Alloy Crankset Shifters Shimano A070 STI Front Derailleur Shimano Claris Rear Derailleur Shimano A070 Brakes Tektro Dual-Pivot Caliper Brakes Brake Levers Shimano A070 STI
Above is what I currently have. I am looking to convert from drop bar to flat bar to use the bike as a casual fitness and commuter bike. All I know is that some parts are road bike specific and may need replacing if I want the conversion done. I hear that the front derailleur, shifters/brake levers (obviously since it currently has STI) and the bar it self. Is there anything else that needs to be changed? I would like someone who has more knowledge in bikes than me to possibly tell me what parts from the above mentioned list needs to be changed. I am not looking to do any upgrades. Just looking for cheap budget parts since it will just be a leisure bike.
Thank you all
