I recently converted my hybrid bike that had flat bars with these

and love them. I have a short torso and almost all bikes do not have a top tube to fit me, regardless of a professional fit. The professionals tell me I need a custom bike. The flat bars always made my hands go numb and my back was tired. Drop bars are ok but after 20 some years of that I wanted to be upright. So, these bars fit me and my body and I can still go fast, enjoy the ride. I just put on my mt bike style shifters to the handlebars but will switch over to bar end shifters later. Wald makes cheaper bars, as does Nitto in a slightly different style, but not much. Just make sure you have room for your hands and shifters if you go that route.
