WIDTH LENGTHWIDTH LENGTH
THIS TECHNICAL MANUAL IS INTENDED FOR USE BY PROFESSIONAL MECHANICS.
Anyone who is not a qualied professional for bicycle assembly must not attempt to install and operate on
the components independently due to the risk of carrying out incorrect operations which could cause the
components to malfunction, resulting in accidents, physical injury or even death.
The actual product may dier from what is illustrated, as the specic purpose of these instructions is to
explain the procedures for using the component.
The 12s chain is not compatible with 10s and 11s drivetrains. Use the 12s chain only and exclusively
with components specically designed by Campagnolo for the Campagnolo®12s drivetrain; using other
combinations could lead to accidents, physical injury or death.
The 11s chain is not compatible with 10s and 12s drivetrains. Use the 11s chain only and exclusively
with components specically designed by Campagnolo for the Campagnolo®11s drivetrain; using other
combinations could lead to accidents, physical injury or death.

The use of sprockets or chainrings which are not marked Campagnolo®can damage the chain. This
may result in its unexpected opening of the chain and cause accidents, personal injury or death.
WARNING!
3 - 12s / 11s CHAIN INSTALLATION
• All connecting and disconnecting of the Campagnolo® 11s / 12s chains should be performed using the
special Campagnolo® UT-CN300 / UT-CN400 (Tab.pag.3) tool. Use of other tools could damage the chain and/
or provoke unexpected chain failure resulting in an accident, personal injury or death.
• The pusher of the Campagnolo®tool UT-CN300 / UT-CN400 is provided with a replaceable tapered tip pin;
if the pin is damaged or it becomes worn, please replace it with the suitable Campagnolo®spare pin UT-
CN301. Failure to timely replace the tip pin can damage your chain, resulting in an accident, personal injury
or death.
WARNING!
3.1 - CHAIN LENGTH FOR 12s MECHANICAL GROUPSETS
For the length of the chain (only with a crankset with 48-32 chainring and 11-34 sprocket box), follow the indications below accor-
ding to the frame chainstay length:
405 - 409 mm: 108 links
410 - 415 mm: 110 links
over 415 mm: 112 links
For any other crankset combination from that indicated above, the chain must be 110 links long for frames with a chainstay length
between 405 and 415 mm.
3.2 - CHAIN LENGTH FOR 12s ELECTRONIC GROUPSETS
• • Determine the correct length of the
chain positioning it on the sprocket and
the smallest chainring and ensuring that
the measurement H (Fig. 1), the distance
between the bottom part of the rocker
and the upper part of the chain, is about
circa 10 - 15 mm.
• In order to avoid malfunctioning of the
drivetrain, the measurement H should not
under any circumstances be less than
3 mm and must not be greater than 22
mm because, with a large sprocket and
chainring the chain would be excessively
taut.

If you have any doubt whatsoever regarding your ability to properly perform any of the operations in this
manual, please take your bicycle to a qualied repair shop.

the measurement H (Fig. 2), the distance
between the bottom part of the rocker
and the upper part of the chain, is about
circa 10 - 15 mm.
• Perform all of the following operations
and remove extra links from the side of the
chain opposite the external link, which is
identified by the plastic band and the adhe-
sive “WARNING!” label (Fig. 4.1).
• n order to avoid malfunctioning of the
drivetrain, the measurement H should not
under any circumstances be less than 3
mm (Fig. 3) and must not be greater than
22 mm because, with a large sprocket
and chainring the chain would be exces-
sively taut (Fig. 4).
!Unlike the 11s chains, this chain does not have the calibrated hole reference adhesive “Warning” label, which
must be left on the chain, therefore it can be truncated from both sides. We therefore recommend leaving the link
that indicates the chain batch, truncating the opposite side.

tongue in open mode (X - Fig. 5)
- fit the link to be opened in tool UT-CN400
(12s) / UT-CN300 (11s / 12s) (Fig. 5)
taking care to end with an internal link:
- clamp the link with the special clam-
ping device (Z) (Fig. 6);

3.5 - INSERTING THE ULTRA-LINK 5-CN-RE600 BUSHING (12s) / 5-CN-RE500 BUSHING (11s)
• Remove the plastic band and the adhe-
sive “Warning” label.
• To install the closing pin ULTRA-LINK
5-CN-RE500 (11s) / 5-CN-RE600 (12s),
place the chain on the bottom bracket
shell.
• Insert the inner link (B - Fig. 8) into the
outer link (C - Fig. 8), and then insert the
guide of the rivet ULTRA-LINK 5-CN-
RE500 (11s) / 5-CN-RE600 (12s) (D -
Fig. 8) into the hole of the link from the
inside of the chain towards the outside.
• Move the chain on to the larger chain-
ring (keeping it on the smallest sprocket),
then position the links to be closed in the
area indicated in Figure 9.

- While exerting a uniform force, screw
in the tool (Fig. 14) so that the bushing
ULTRA-LINK 5-CN-RE500 (11s) / 5-CN-
RE600 (12s) (E) has completely entered
the thickness of the chain.
Note
In order to minimize the possibility of
damaging the chain irreparably, DO NOT
TIGHTEN the tool beyond the beat. Let
the bushing ULTRA-LINK 5-CN-RE500
(11s) / 5-CN-RE600 (12s) (E) protrude
0.1 mm from the inner side of the chain
(Fig. 13).
- Insert the protruding part of the guide
into the hole provided at the base of the
tool and split it by bending (Fig. 14).
The terminal part of the split guide must
always remain inside the bushing.
- Remove the clamping device and remove
the chain from the tool.

- Free the joints as required with delicate
lateral bending of the links (Fig. 24).
A poorly joined chain could open suddenly when using the bicycle, causing accidents, physical injury or
death. If you have any doubt over your ability to follow the instructions in this manual correctly, contact a
specialist mechanic.
WARNING!
2.4 - CHAIN OPENING
If it becomes necessary to open and close the chain (which can be done only twice), use only the special
Campagnolo ULTRA-LINK 5-CN-RE500 (11s) / 5-CN-RE600 (12s) pin with Campagnolo UT-CN400 (12s) / UT-CN300
(11s / 12s) tool.
The use of pin produced by different manufacturers can damage the chain. A damaged chain can break, even
suddenly, and cause accidents, injuries and even death.
WARNING!
Opening and closing the chain on more than two occasions can result in the chain unexpectedly failing while
riding, resulting in an accident, personal injury or death.
WARNING!
- Get the special Campagnolo® bushing ULTRA-LINK ULTRA-LINK 5-CN-RE500 (11s) / 5-CN-RE600 (12s).
- Only and exclusively use the tool UT-CN400 (12s) / UT-CN300 (11s / 12s).
- Identify the opening link on the chain; this must be different and away from the one used for closing the first time (a link that can be
recognizable from the impression showing the production batch).
Note
To open the chain, carry out the operations indicated in chapter 3 “Chain installation”, using the Campagnolo® tool UT-CN400 (12s)
/ UT-CN300 (11s / 12s) only.
