okay, i skipped school today just to practice a trick that i started to do yesterday. 360, i can spin around fine, but its just the landing, i've only landed it like 5 times, for some reason my rear wheel keeps dropping as i'm spinning around. and i'll either land with my rear wheel almost directly below me or i just bail in mid air to save myself from a nasty crash. and another thing are my x-ups, they are fine on my mountain bike, but when i do them on my bmx, my bars always hit my knees. should i get shorter bars or just learn to move my knees somewhere. thanks guys
