With the introduction of the new 11-speed drivetrains, Campagnolo aimed to reaffirm its ability to innovate and to produce components with benchmark features.
All the new components of the 11-speed drivetrains have been completely redesigned and conceived to interact with each other. As always happens with entirely new products, the product changes also lead to new fitting and servicing operations.
While it is always important to follow attentively the instructions for correct assembly and correct servicing, in the case of a completely new component all this becomes absolutely mandatory.
Only this approach (which has nothing to do with the experience or expertise of the mechanic who performs the operation) makes it possible to preserve the characteristics of the product in terms of both performance and safety for the user.
Specifically, as regards the new Chorus and Record 11-speed chains, we have verified some problems in the field that arose from incorrect installation, with consequent serious danger.
We therefore remind you that in order to install the Campagnolo 11s chains, as described in our assembly instructions, it is absolutely mandatory to use the dedicated UT-CN300 tool.
In fact, only by using this tool it is possible to perform the riveting of the closing pin (5-CN-RE500) included. We should point out that without this riveting operation, the pin can protrude from the link, causing the automatic opening of the chain with the due consequences.
For your safety and to ensure the maximum lifetime of your 11-speed chain, please make sure that the chain is correctly assembled/disassembled by your reliable mechanic.
ATTENTION: If it is absolutely necessary to remove the chain (e.g. for replacing components, changing the frame, or other), please have this done by your specialised mechanic.
In any case, we strongly advise against removing the Campagnolo 11-speed chain for cleaning.
