Hi all. New to the forum and road biking. 

Query. This isn't something I definitely intend to do but wanted some advice nevertheless. So currently have a set up as follows: 

drop bars

full 105 drivetrain 

rs505 hydraulics

if I intended to do a flat bar conversion, could I just swap out the bar, levers and shifters to something compatible with the existing, or is there something else I have overlooked????

If you're wondering why I want this. Can't seem to get on with the position drop bars put me in. I am trying a shorter stem this week which I will also flip to bring things a little closer but we shall see.
