"more common tricks ie. Riding a wheely, jumping a curb, riding backwards"
...something you can do on any fixed gear.
-gear ratio: if you had to stay in one gear ratio on your road bike, what would it be?
-handlebar setup: on your drop bars, what position do you like to be in most for relaxed riding?
-wheelset/tires: what's your budget?
-brake/no brake: better safe than sorry...at least when you're starting out
common sense, man.
