Closing chain with Snap Lock:
• Fit the shortened chain, bring the ends
together and connect with the Snap Lock.
Place the outer plate on one pin
(Fig. 6) .
• Gently flex the chain until the outside
connector plate snaps into position over
the second pin
(Fig. 7) .
Caution:
• Make sure plate is fully seated in the
pin channel and plates are parallel to
each other.
• If movement of the connector plate is
noticed a new Snap Lock must be used.
• Always use a new Snap Lock when
fitting a new chain. Failure to shorten
the chain properly or to lock it exactly
into place may cause damage to the
chain and eventually total chain failure,
material damage or the rider to fall off
his bicycle resulting in injury.
Closing chain with 3pcs Connection Link:
• Fit the shortened chain, bring the two
ends together and connect with the
chain lock. The chain lock consists of an
outer plate with pins (1,
Fig. 8) , an outer
plate (2) and a retaining spring (3).
• Insert outer plate with pins (1) into the
chain ends, attach outer plate (2) and
press chain lock together (1+2).
• Attach retaining spring (3) with the
closed end of the retaining ring pointing
in the direction of chain travel
(Fig. 9) .
• Slide retaining spring in the direction
of arrow (4, Fig. 9) to engage it in the
grooves in the pins.
Closing standard version with clamping pin:
Fit chain, bring the two ends together and
press pin
(Fig. 2) through with assembly
tool. The pin must extend by the same
amount at both outer plates. It must be
possible to move the connecting link
slightly.

• Regular lubrication will extend the
chain's service life.
• Apply oil to the chain rollers and allow
to work in.
Clean dirty chains before oiling. Do not
use any grease-dissolving or acidic
agents. Cleaning agent must be rinsed
off after a few minutes with water.
• Apply oil after chain is completely dried.

Chain length:
• Shorten chain to the length specified by
the derailleur manufacturer.
SRAM derailleurs:
• Place chain over largest front chain-
wheel and largest rear sprocket and add
2 links or 1 link + Power Link
(Fig. 1) .
• For rear suspension frame, position the
rear suspension for the greatest chain
length required.
Closing standard version with clamping pin:
Fit chain, bring the two ends together and
press pin
(Fig. 2) through with assembly tool.
The pin must extend by the same amount
at both outer plates. It must be possible to
move the connecting link slightly.
Power Link connecting links:
Caution:
• Use only for SRAM chains, use as specified,
to avoid material damage or the rider to
fall off his bicycle resulting in injury.
• Use only Power Link for closing Hollow
Pin and Cross Step chains (no pin).
Closing:
• Fit chain, bring the ends together and
insert both halves of the Power Link into
the chain ends.
(Fig. 3)
• Press both halves of the Power Link
together (Fig. 4) and lock in place by
pulling the chain apart. (Fig. 5)
Opening:
• Press both plates of the Power Link
together (Fig. 4) while sliding the chain
ends together (unlock). Remove the two
halves of the link from the chain ends.
Caution:
Always use a new Power Link when
fitting a new chain. Failure to shorten the
chain properly or to lock it exactly into
place may cause damage to the chain and
eventually total chain failure, material
damage or the rider to fall off his bicycle
resulting in injury.
