i think risers can be very stylish and they're fine if you prefer an upright riding position; however, if you prefer an upright riding position, a road/track bike is the exact opposite of what you need. and that notion opens up a topic that i don't think needs to be discussed here (why people who aren't comfortable on road/track bikes put themselves through the discomfort simply for aesthetics).

you may be able to barspin better than someone using horns or drops, but let's a have an uphill sprint and see how many people riding risers can crank as efficiently as people with horns or drops.
