I just bought a Profile Design integrated TT stem/bar/aerobar with brake levers for $50. I got the Dura-Ace 9 speed barcons to go with it earlier for $45. I'm thinking of running it on my Miyata carbon wrapped ss/fixie for awhile. Once I finish building and trying out the Mercier frame I may have to sell it because of it's size - 64cm. I'm thinking of making the Miyata my race style bike instead. These bars are set up like these.
if that link fails they are similar to these newer ones. http://www.cbike.com/profile_design.htm
That would allow me to keep the Schwinn Prelude as the new fixie/ss. It's on the small side for me but isn't slightly small better for fixies? She's 22.2 lbs as shown so she should be almost as light as the Miyata at 17 lbs.
