I experimented with this idea on two bikes I was flipping a few years back. I actually really liked the way it looked and it definitely provided the rider with a comfortable riding position. Plus you could always just loosen the brake lever and rotate the bars back to a standard bullhorn position. Figured it was a low risk proposition. Both bikes sold within the week if I remember correctly and both to girls as a matter of fact. Great, little bar hopping bikes.

PS - Kinda wish I still had that 'ice pink' tempo
