I wanted an extra light sprocket that did not have to be babied. Capable of light street and skatepark trickery.

This design is actually a morph from the original Tree sprocket. We enlarged the holes and got rid of unneeded material, which gives it a very impressive strength to weight ratio. It is made of 5/16'' thick 7075 t6 aluminum.

The sprocket accepts both 1/8 and 3/16 chains. Most sprockets are machined with thin and short teeth but the Tree sprocket teeth are machined to .13'' wide for maximum tooth strength and .27'' tall for a smoother running drive train. And they are the right height so they can not get hit during sprocket tricks. These teeth are very helpful when riding a loose chain because the taller teeth keep the chain from derailing. These teeth have been modeled after the tooth shape used for industrial machinery. In industrial situations this engineered tooth shape keeps machinery running quietly and smoothly at very high RPMs. For BMX it makes the smoothest running sprocket ever made.
