Furthermore, it is an ideal choice for riders who spend hours in the saddle across mixed terrain conditions, while still maintaining the racing performance you would expect from Campagnolo. Engineered for intense road cycling, the Campagnolo Chorus 12 Speed Disc Groupset gives you high-quality 12 speed components combined with industry-leading technologies. This means you’ll have everything you need to upgrade your drivetrain.Campagnolo Chorus 12 Speed Rear DerailleurFeaturing a hard-wearing aluminium build, this rear derailleur is engineered for toughness and reliability as you clock up the miles on your road bike. Campagnolo has also developed this model for constant precision, even on rough roads by positioning the spring between the upper body and the pivot to absorb vibrations and ensure the chain always rests properly on the sprockets. Another highlight is the pulley wheels on the 12 tooth derailleur cage allow your chain to move more smoothly for efficient shifting. The initial position of the rear derailleur can be adjusted to suit any cassette plus it offers easy wheel replacement by positioning the rear derailleur further back, making it easier to slide the wheel out and replace it.12 Speed Rear Mech with 3D Embrace TechnologyThe updated Chorus rear derailleur benefits from the same technology and design of top-end Campagnolo products, incorporating the sophistication and performances of the 12 speed Super Record and Record. With just a few changes in the materials used for its construction, like the external plate and derailleur cage in aluminium, the Chorus version produces exactly the same performance as the two more expensive groupsets with the addition of just a few extra grams. Chorus brings with it the same technology as the next level up, like the optimised trajectory on bigger cassettes and fantastic 3D Embrace technology. The latest evolution in Embrace technology not only keeps the rear derailleur vertically aligned in the perfect position for each sprocket, it now makes the upper pulley wheel advance perfectly in the direction the bike is advancing. 3D Embrace technology and 12 teeth pulley wheels make this rear derailleur suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected.Features: Material: Aluminium Use: Road Cage Size: Medium Speed: 12 speed Constant precision 3D Embrace Technology Optimised Trajectory Optimised Return Spring Easy wheel replacement Weight: 240gCampagnolo Chorus 12 Speed Front DerailleurOffering smooth and reliable shifting, this 12 speed front derailleur features updated cables and housing along with performance-enhancing technologies. It incorporates the same design that separates the upper from the lower semi-rod, eliminating the free stroke for more immediate, responsive upshifting. The design of this 2×12 speed front derailleur and its trajectory angle means wide tyres measuring up to 32mm can be used, while its revised cage design and dedicated positions for each gear ensure extremely precise and fluid derailleur performance.Features: Use: Road Speed: 12 speed Mount: Braze-On Ideal for wider tyres Design optimised for inner cage Double-position fixing of the cable Optimised position for every engaged sprocket Weight: 94gCampagnolo Chorus 12 Speed Hydraulic Disc BrakeWhether you’re clocking up the miles with your local road club or competing in a triathlon, time trial or cyclocross event, this hydraulic disc brake is engineered for dependable braking and shifting performance.
