Turn the rear wheel slowly until the chain is fully stretched.
At the halfway mark on the swinging arm (see adhesive label on arm), press the chain upwards with one finger and measure the amount of slack.
The lower section of chain must not give by more than 30 mm/1.18 in. when pressed at the point indicated.
To tension the chain:
Loosen the nuts (1) on the ends of the wheel spindle.
To tighten chain tension, tighten the adjuster screws (2) on both sides of the swinging arm by equal amounts. To loosen the chain tension, unscrew the adjuster screw (2). Push the wheel forward when slackening the chain.
Caution! Incorrect chain tension can cause rapid wear of transmission components.
Check that the wheel is aligned by checking that the position on the notches of both sides of the swinging arm is the same.
Tighten the nuts (1) on the wheel spindle to the torque specified.
Tighten the adjuster screws (2) to the torque specified.
Check the torque of the nuts (3) fixing the rear sprocket to the wheel flange. To do this with the wheel mounted on the bike, lock the bolts on the other side in position with an 8 mm jointed socket spanner while you tighten the nuts.
