2012 Campagnolo Chorus 11 Speed Front Derailleur features the same technical design as the Campagnolo Record 11 front derailleur but uses alloy rather than carbon plates. Like its big brother's design, the Chorus front derailleur includes an Ultra Shift outer plate and Z-shaped inner plate that are stiffer and results in more accurate and quicker shifting. The new M-brace body is more rigid than older designs and anti-friction treatment to the inside of the plates helping to reduce prevent chain wear. The braze-on version weighs 76 grams.
