After 7 years and many (4?) attempts, I finally found comfortable handlebars for the Screamin' Salmon, my fixed gear.
It finally involved:
1) buying handlebars in Amsterdam
2) sawing off the end of those handlebars
and 3) buying a new extended high handlebar stem with minimum reach
The handlebars are right at seat height. Maybe an inch higher. This allows upright posture. As I wrote once before, unless you're sprinting, fixed gears mean you can't really rest your weight on your feet (because you can't rest your feet). As a result, there's a lot more weight on your ass and hands. On drop handlebars, weight is more evenly divided between feet, seat, and hands. Take feet out of that equation, and well, it just doesn't work. Hands aren't designed to take that weight.
And yet I see people with fixed gears all hunched over drop handlebars. I don't get it. Seems like torture to me. And I like drop handlebars.
The angle on my handbrake isn't quite right. I want the whole thing lower, but rotated that way, the brake handle shoots out a funny angle. I'll have to play with that a bit.
