[QUOTE=benfit;12382978]Yea, but still, the system is old and I don't really like the gear changing, so I want to make a single-speed bike, but since fixed gears are better for long, straight distances than normal single speed, i decided to make a fixie

Where'd you hear this? Most touring bikes are geared and have freewheels.
Are you sure you aren't cashing in on a new trend?
Your dropouts would work, and yes in theory, all you need is a proper rear track hub.
Projects like this are (almost) always more work than they seem, my conversion had many kinks and problems, but it was a learning process.

I guess you should ask yourself if you really want to go fixed, and if so, hit up Sheldon. I went suicide hub (strapped for cash), and had to respace the rear axle, retension the wheel, overhaul everything, replace things with stripped threads, and even had some bent tubes. Choose wisely
