4. How to use the B-tension adjustment screw
Mount the chain on the smallest chainring and the
largest sprocket, and turn the crank arm backward.
Then turn the B-tension adjustment screw to adjust
the guide pulley as close to the sprocket as possible
but not so close that it touches. Next, set the chain to
the smallest sprocket and repeat the above to make
sure that the pulley does not touch the sprocket.

5. SIS Adjustment
(1) Operate the shifting lever to move the chain from
the top gear to the 2nd gear.
* If the chain will
not move to the 2nd gear, turn
the outer casing adjustment barrel to increase the
tension-----
➀ (counter clockwise)
* If the chain moves
past the 2nd gear,
decrease the
tension---

(2) Next with the chain on the 2nd gear, increase the

forward. Stop turning the outer casing adjustment
barrel
just before the chain makes noise against
the 3rd gear.
This completes the adjustment.

In order to realize the best performance, we
recommend that the following combination be used.
Note
• For smooth operation, always be sure to use the
specified outer casing and the bottom bracket cable
guide.
• Grease the inner cable and the inside of the outer
casing before use to ensure that they slide properly.
• The tension pulley has a mark which indicates the
direction of rotation. The side with the arrow is the
front side.
• Because the high cable resistance of a frame with
internal cable routing would impair the SIS function,
this type of frame should not be used.
• The end of the outer casing which has the
aluminum cap should be at the
derailleur side.
• For any questions regarding methods of installation,
adjustment, maintenance or operation, please contact
a professional bicycle dealer.
For the best SIS performance, periodically lubricate
all power-transmission parts.
