[. . . ] Because of this, an excessive load may be placed on the drive system if the chain length is too short. Set the length of the chain by adding two links to the chain when the rear suspension is at a position where dimension "A" is longest and the chain is on the largest sprocket and the largest chainring. If the amount of movement of the rear suspension is large, the slack in the chain may not be taken up properly when the chain is on the smallest chainring and smallest sprocket.

Loosen the outer casing adjustment barrel until the chain touches the 3rd sprocket and makes noise. (counter clockwise) * Turn the outer casing adjustment barrel together with the outer casing adjustment barrel cover. Low adjustment screw Best setting The best setting is when the shifting lever is operated just enough to take up the play and the chain touches the 3rd sprocket and makes noise. * Return the lever to its original position (the position where the lever is at the 2nd sprocket setting and it has been released) and then turn the crank arm clockwise. If the chain is touching the 3rd sprocket and making noise, turn the outer casing adjustment barrel clockwise slightly to tighten it until the noise stops and the chain runs smoothly.
