Comfortable drop and too
by Anonymous

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.
