Installation Notes:
1. The BCD of the tooth plate is 104. The rider who purchased it carefully confirms that his crank is 104BCD (the diameter of the circle formed by the points of the four disk nails is 104 mm). Don't make a mistake, otherwise it will not be installed.
2. The screw holes of this tooth plate are designed without sinking grooves, and the three-disk and double-disk disk screws to be modified can be directly used for the disk screws, and there is no need to purchase additional disk screws.
