The thing that makes a bicycle a bicycle and not a scooter is the drive train. To celebrate the joy of cranking that simple machine and the introduction of our three pricing levels beginning with our sprockets, we are going to give away three sprockets, one of each style: Lite, Original, and 4130. Find out how to win!

The rules are simple. Get a picture of yourself that shows you cranking, roasting, roosting, gapping or just enjoying the ride on the bicycle. Be creative; you can blast through a pile of leaves, boost a curb, roost some dirt, or sky a quarter. Winners will be picked based on capturing a nostalgic feel of BMX and not on trick difficulty. To submit an entry go to the Tree Facebook, like our page, post your pic as “Win a Tree Sprocket” and tag us in the pic. Contest is open until November 6th 2011.
