Forgot to mention that since you reside in Hawaii, you are absolutely allowed a computer on a fixie. If anyone gives you crap about it, it's the little-known "riding fixie on volcano" rule. Man, I miss that place. You should try that 32 mile downhill ride on the volcano (can't remember its name) in Maui. On your fixie. Maybe a 55 or 56 tooth in front and an 11 in back. No brakes, natch.
