These are Easton compact bars, and are (aero!) flat on top. My previous bike had a slightly flattened top bar, and I love these even flatter bars. The compact drop makes it easier to ride in that position for extended periods, no doubt about it.
I only have a basic CatEye computer, and the only downside with it is that it doesn't transfer easily between bikes because of the wheel and crank sensor. Otherwise, it is small, light, doesn't need charging and tells me everything I want to know and there is no app tracking me.....
Bonking. Is really unpleasant, and it is amazing how quickly you can go from "Im the fastest thing on the road" to "I cant get home". Pay special attention in the heat.
