For all riders using Campagnolo 10 speed drivetrains, the availability of compatible parts is getting increasingly harder to find with every passing season. Campy has decided to dedicate the Centaur group of components to service the needs of all 10 speed users. They have taken the technology of the 11 speed components and used it for an updated version of 10 speed with the current line-up of Centaur components. Even though it is not Chorus or Record quality, the fact is, Campy 10 speed has never functioned better.
The outer cage of the Centaur derailleur completely wraps and envelopes the body for reduced flex and increased torsional rigidity. Slightly improved geometry improves shifting prowess while keeping it backwards compatible with older 10 speed drivetrains.
The cable fixing bolt and tension bolt are durable steel while the derailleur/frame fixing bolt is lighter weight red anodized alloy. Pulley wheels are rubberized similar to higher end Campagnolo derailleurs to help grip the chain while reducing friction for smooth glide while in use..
