If available in various colors, it is possible to select the color together with the number of teeth.

High quality and long lasting chainrings, in Ergal 7075T6, entirely produced on CNC machines.Characterized by an exclusive tooth profile designed by AFAM and milling at the base of the teeth to generate centrifugal self-cleaning, thus allowing the chain to work on the entire tooth surface in case of use on muddy or sandy terrain.
The special second generation three-dimensional "snowflake" design has a particular low relief that reduces the thickness of the crown in some areas of the central part, to maximize weight savings without sacrificing reliability.Available in two different finishes:with colored surface anodization or with hard anodizing, "gun metal" coloring: this hard finish significantly reduces crown wear.

By choosing the ratios, 1 front sprocket cog is equal to about 3 rear sprocket cogs (the exact ratio is given by: number of rear sprocket teeth / number of front sprocket teeth).
The above stated, ratios have to be chosen in a way that a max. difference of 2 cogs is not exceeded. This way, you can always keep the same chain length. The Kawasaki ZX-10R Ninja is an exception: a rear chain with over 1 tooth more than the stock one cannot be used, since length of stock chain will not allow that. Remember that if you want more acceleration you have to mount a rear sprocket with more toothing, or a front sprocket with lower toothing. Ratios have to be necessarily and exclusively chosen by yourself. It is usual to mount a rear sprocket with 2 teeth more than the stock one, but that is however a medium choice which does not mean to be satisfying to everybody.
In a circuit, generally the right final ratio will be that allowing to achieve, at the highest gear, about 200 rpm more than the max power rate, always staying 200 / 300 rpm under the maximum rate the engine can reach. This way, you can take advantage of the trail of the driver who is preceding you.
Choosing the final ratio, remember that the bigger it is, the more the acceleration will be. But if it is too big, you will lose speed. If on the contrary the ratio is too small, you will lose acceleration and will not manage to reach the maximum speed.
