I just bought a Profile Designs Stoker bar, pretty much identical to the one pictured, for $29.95 or so from trisports.com. Performancebike.com has the PD Aero Wing bar for about the same. The stoker bar is straight across the tops. Some of the aero bars slope down from the stem to the corner then turn straight forward. The Tsunami Bull Horn bar at chucksbikes.com (which is actually a relabelled Syntace bar) for $10 has this slope. It may be fine for some, but I couldn't tolerate it. I always thought such a slope would be perfect since it mimics the angle your hands assume if you hold them relaxed in in front of you. Unfortunately it didn't work that way for me as it seemed to place undue pressure on the outside of my hands when I rode on the bar tops (my normal position). The stoker bar is working out much better. If you go to trisports.com click the Clearance button. They only had 40, 44, and 46 when I ordered mine which was fine since I wanted a 44 anyway.

William, cutting off a regular bar is OK, but be aware that if you want to use the bar end type brake levers it will be a problem. The circular cross section of the tubing is deformed by the bending process so the bar ends won't go in. Not even close. Maybe if you have access to tools to swage the tubing back out to round or if you don't plan to use bar end brakes. I had mine set up for a while with a cut off bar pointed down, using regular road brake levers. It is actually a pretty cool look, but I had already purchased a pair of black bar end levers I wanted to use so I got the stoker bar.

What is it that makes bull horn bars just look "right" on a fixed gear? I thought I was being original when I decided to put them on mine then I started noticing a number of fixed gear bikes on the street with them.
