Campagnolo's conversion to 11-speed requires a new technique to be used when installing Campy chains in comparison to 10-speed. The Park CT-11 Campagnolo 11-speed Chain Peening Tool can be used for this most important of steps.
The new 11-speed Campy chains are not unlike what we're used to. However, the installation rivet must be peened, or deformed, after it is pressed into the outer plates. This crucial step ensures that it will stay in place, something we think is important. The CT-11 is not to be used to break chains or even press rivets. For those mundane tasks, use the standard Park CT-4 or CT-4.2 chain tools. The Park CT-11 Campagnolo Chain Peening Tool comes in Park Blue and features ergonomic handles for comfort every time you use it.
