Refer to the first post in this thread regarding a suggested order in which to buy chainrings and cogs: http://www.bikeforums.net/track-cycl...ack-racer.html

You will not need a full kit on day 1 at the track. 48t, 49t, 15t, 16t will get you through your first couple of months and add a 50t and you could finish the entire season.
