so are we to treat this as the "what don't you like about my bike" thread? i don't know about you're area's landscape but 44 x 17 is a really weak gear ratio, unless you are new to biking/fixed or the area is incredibly hilly, i'd run a 16 rear at the biggest, even though it sounds like your current ratio is fine. Further, as previously stated, PLEASE fix your headset spacing. Also, i would invest in a better wheelset when funds allow. while those are relatively decent, i have a friend that ran those same wheels and completely thrashed them with just everyday riding. And, of course, get a new fork so that you can run a front brake.
