Maybe your race is not on all the way, my bike had that problem for soo long and it fucked everything up, but yesterday i finally made it fit perfect and its not gay anymore.
its like REALLY slow
its pretty hard just to spin the deck in a whole circle
like it feels as if its really tight
but its still all shakey
im just going to see if the bike shop knows whats up
if not im just going to buy a new headset
