Campagnolo

Chorus 11 Chain

Like the Record 11 chain, the Campagnolo Chorus 11 Ultra Shift chain is 5.5mm wide. This narrowness means it has less interference with adjacent sprockets and chainrings, which makes it quieter and quicker-shifting than previous generations of Campagnolo chains. The re-shaped Ultra Shift outer links contribute to its quick shifting, plus it shaves a few g's to make it weigh in at 252g. Plus, a re-formulated outer link material gives it 20% greater longevity.

Another similarity to the Record 11 chain is its Ni-PTFE treatment, giving it added smoothness and durability. In fact, the only difference of note between the Record 11 chain and the Chorus 11 chain is that the Record version has hollow chain pins, and the Chorus pins are solid. This nets a 14g weight savings for the Record. But you can rest assured that the Chorus chain shifts every bit as crisply as the Record version.

The new Ultra Link system gives the chain a high retention force to protect you from the consequences of ham-handed shifts (something we've all done when we're beaten up near the end of a hard ride). But please note one critical change due to Ultra Link: The Chorus 11 chain requires the use of a Campagnolo UT-CN300 chain tool for installation. Yes, this tool is pricey, but the narrowness of the chain necessitates precise installation. Note also that the Chorus 11 chain is compatible with all Campagnolo 11 speed drivetrains -- Super Record, Record, and Chorus.

The actual weight of the Campagnolo Chorus 11 Chain is 252g.
