For 2015, Campagnolo components is discontinuing its Athena EPS drivetrain and will introduce a Chorus EPS group, which sports more carbon and a lower weight compared to the Athena EPS.

Chorus

Campagnolo Chorus EPS system
The Campagnolo Chorus EPS system has a different battery and connectors than Record EPS, making it impossible for riders to mix and match components.

 

Campagnolo Chorus EPS derailleur
The Chorus EPS front derailleur, which puts out 52nm of torque, has a three-dimensionally molded upper and a steel shifting cage.

 

Campagnolo Chorus EPS crank
On of the most striking changes for 2015 is the new Chorus and Super Record four-arm cranksets, which sport eight chainring bolts. Four bolts per chainring provide back pressure, which better reinforces the big ring to handle those powerful 52nm shifts. The new design, like Shimano’s four-arm design, allows one crankset to be compatible with both compact and standard chainrings.

 

Campagnolo Chorus EPS rear
The upper and lower bodies are made of 3D molded carbon fiber.

 

Campagnolo Chorus EPS brakes
The new Chorus EPS brakes use more steel than aluminum, compared to previous Chorus brakes, in an effort to lower the group’s price. Still, the design requires no tools for swapping brake pads, like Record.

 

Campagnolo Chorus EPS cassette
Chorus EPS can use up to an 11-27 cassette and is made of nickel-plated steel.

 

Super Record

Campagnolo Super Record 2015
The new for 2015 is a completely redesigned Super Record mechanical group. The Super Record drivetrain carries the highest price of any mechanical group, but will still be comparably priced to the current version of Super Record.

 

Campagnolo Super Record shifters
The shift lever internals are all new and are incompatible with any other Campagnolo drivetrain, for now.

The new hood shape of the Super Record levers has a dual-durometer rubber to add cushion, but it feels similar to previous Ergo levers.

 

Nearly every piece of the rear mechanism is carbon or titanium, while the jockey-wheels have ceramic bearings. It weighs 160 grams.

Campagnolo Super Record derailer
The new front derailleur gets a longer lever arm that closely resembles Shimano’s 11-speed derailleurs.

 

Campagnolo Super Record dual pivot brakes
The Campagnolo Super Record dual pivot brakes remain unchanged.

 

Campagnolo Super Record cranks
The Super Record crankset resembles the Chorus crank, but uses a hollow left carbon crank arm compared to Chrorus’ solid carbon arm.

 

Campagnolo Super Record crank teeth
The Super Record crank uses eight chainring bolts that tighten into the crank spider. This stiffens the crankset when shifting and makes the crank convertible between standard and compact gear ratios.
