Installation of the chain rings
Smooth shifting will not be possible if the chain rings are incorrectly
installed, so be sure to install them in the correct positions.

outward, and the markings on the small chainrings should face inward.
Install so that the markings are in the
positions shown in the illustration.
For the FC-2203, the tooth number
marking on the largest chainring should
face outward, and the markings on the

should face inward.
