For Zach's subtle fade Open road bike. The saddle, frame bag and bar tape are in a dark chocolate kangaroo leather with subtle fade perforations from light olive green to cool grey. Zach went to a lot of trouble to make a template for the bag shape including a narrower piece to indicate how much the tubes recess into the bag cavity compared to the external shape of the main side panels. Theoretically the bag should fit perfectly, my fingers are crossed.
