Do you have a passion to be out on the trails with some of your best friends taking on the world? That is what we thought about when we created this amazing mountain bike tread ring. The details of this ring are amazing and it really does look like a mini version of a mountain bike tread. This gray ring is a narrow style ring measuring in a 5mm so that the character and true detail come through on the ring. It is made from lightweight and durable titanium and has a sandblasted and satin finish.
