Campagnolo Record chain 11-speed

A special treatment ensures their ease of movement. With the new sprocket spacing, we have reduced the chain width to 5.5 mm and a new material is used for the outer chain plates. The chain pins are hollow inside to reduce weight without compromising durability. The special tool UT-CN300 is required for assembly. The nickel-PTFE surface treatment ensures smooth running properties and a long service life. The Ultra-Link™ chain locking system guarantees durability and optimal function on the 11s sprockets. The special tool UT-CN300 (Item 759001) is required for assembly. - 5.5mm wide - Ultra-Link chain closure system - Outer plates made of new special steel - Nickel-PTFE antifriction treatment - hollow chain pins DANGER! All operations for closing and opening the Campagnolo chains 11S must only be carried out using the Campagnolo® UT-CN300 tool. Using other tools can cause damage to the chain. The slider of the Campagnolo® UT-CN300 tool is equipped with a conical tip tang. If this tip is worn or damaged, you should replace it with the Campagnolo® UT-CN301 replacement tip, which is available as a spare part. If the pin is not replaced in time, it may damage the drive chain. The use of sprockets and chainrings other than "Campagnolo®" can damage the drive chain. An incorrectly installed chain can suddenly break while the bike is being used, causing accidents that could result in physical injury or even death. If you have any doubts about your ability you should contact a specialist bicycle mechanic. Instructions can be found at: http://www.campagnolo.com/repository/documenti/de/7225363- tool_UT-CN300.pdf
