Reason For Making It
We are reintroducing this sprocket after lots of public demand. This is the sprocket that changed the BMX sprocket market and is currently the strongest sprocket available!
Why It's Made This Way
It has 5 different crank arm bolt positions to help extent the life of the sprocket. The sprocket is machined in a way that removes material from the triangle shaped holes that is not needed and leaves the material necessary to form a structure of high strength to weight. Classic looking design has a timeless appeal.
