Official Boone single speed cogs machined to order out of aerospace grade titanium here at our shop in Kennesaw, GA. 14 through 22, and 24 tooth variants are currently available. Refer to the reference image to determine the kind of anodizing you would want for your cog. We can do any voltage 1V to 100V for solid color cogs or even a gradient from any voltage to another in either linear or radial fade styles. Keep in mind that for radial fades, the higher voltage in the gradient will be towards the teeth of the cog. If you have any questions regarding anodizing colors, feel free to contact us via the facebook messenger icon at the bottom right of this website, Instagram messenger, or email at email@example.com and we will get back to you as soon as possible with an answer. When ordering, make sure you specify which color you are interested in in the comments section at checkout or else we will assume you want the linear rainbow fade!
