Mildly Ergonomic and kind of a deep drop

I like to be stretched out a bit on my bike. That means a longer stem and maybe the seat pushed back a bit. This means I probably have too much weight on my hands so I'm include to ride with ergonomic handle bars and grips on my bicycles. This one sort of works, but the top isn't really very wide so I'm back resting on the hoods. The drop is pretty deep, so I don't spend too much time in the drops even when its called for. That all said, if you like a shorter cockpit that I do it will probably work for you.

Comfortable drop and too

I didnt want to go full on aero on the handlebars and wanted something that would make it more comfortable on the hands while climbing on the tops. This fit the bill and the drops are feel great as well.

Comfortable and Well Priced

Flat top makes it comfortable when climbing up hills. Hood positioning is good, but I would had preferred a lower ramp angle so that when transitioning to the hood is level. Otherwise, all other positioning if very good and the price was much lower than other similar bars.
