Shift Differently, Shift Better, Super Record 12-speed goes electronic!
Campagnolo Super Record EPS, the feather in the cap of Campagnolo® innovation thanks to the technologies, materials and expertise behind the design of this groupset, consolidates its benchmark role by moving up to a 12-speed.

Leading the way for 8, 9, 10, and 11 speeds and, more recently, 12 speeds, Campagnolo has always been a pioneer in innovation for racing bike transmission. The recently introduced Super Record and Record mechanical drivetrains marked not only a new era in the technology of the mechanical groupset, but also made the way for what was to become the electronic version of the Super Record 12-speed groupset. EPS technology was tested on the field by cyclists and before its launch on the market, it was subjected to the usual testing by the Campy Tech Lab in the most demanding lab in the world: the World Tour.

This very popular groupset is now available in a 12-speed option with its V4 version in Power Unit electronic components and interface. The groupset has been redesigned to adapt perfectly to the 12-speed technological frontier and to the 11-29 and 11-32 cassette combinations introduced in the mechanical version. Fast shifting, always precise and effortless for the cyclist, and a very gradual gear ratio are just some of the extraordinary characteristics of the EPS groupset.

The Campagnolo Super Record EPS 2x12-speed groupset with hydraulic disc brakes consists of:

Super Record EPS Disc Brake Ergopower 2x12-speed with Flat Mount disc brake calipers
Super Record EPS front derailleur 2x12-speed
Super Record EPS rear derailleur 2x12-speed
Super Record cassette 12-speed
Super Record chain 12-speed

Campagnolo Super Record EPS
Campagnolo EPS, Electronic Power Shift, is an evolved electronic drivetrainsystem that, through artificial intelligence (DTI, Digital Tech Intelligence), is capable of translating the actions that the cyclist performs on the levers into digital signals, process them and control the coordinated movement of the front and rear derailleur. The EPS system possesses electronics that are centralized and not located in the parts, digital intelligence that communicates with the components and continuously sends feedback, and controls them. Centralized electronics means more stability to the system and less risk of failure and breakdowns due to falls. If malfunctions encounter, the EPS system is capable of automatically detecting a whole range of them. The On Board Diagnostic shows with different colors in a RGB-LED where a malfunction is detected.

Super Record EPS Rear Derailleur
In the same way as the front derailleur, the rear one also exploits many developments achieved for its mechanical 12-gear predecessor. The same 45° trajectory angle corresponds to an improved change of position that electronically improves chain engagement specific for each sprocket. Better power transmission and less wear and tear of consumer transmission components are just two of the advantages. Compatible with the two 11-29 and 11-32 cassettes, the two pulley wheels have 12-tooth design and the 72.5 mm derailleur cage ensures perfect performance. The slimmer, sturdier structure of the resistant derailleur cage gives more space between the derailleur and the spokes, making it easier to adjust. Moving the chain onto 12 sprockets in the cassette calls for greater precision, given the increased number of chainrings in the same space.

Super Record EPS Disc Brake Ergopower
The shape of the updated brake lever with its new 12-speed design is the result of painstaking studies carried out in the Campy Tech Lab to ensure that, together with positioning of the downshift lever, the cyclist has an intuitive, practical, comfortable "control center". The Ergopower Super Record EPS DB controls incorporate the AMS (Adjustable Modulation System), which allows setting of the desired mode and reach adjustment to position the brake lever an optimum distance from the handlebar.
Multishifting technology, namely the option to change several sprockets with in a single shift is now applied to all the 12-speed cassettes. Cyclists can use the MyCampy app to personalize the Super Record EPS groupset. The Ergopower control also offers the cyclist total control over how the transmission works thanks to the MODE button (found immediately behind the downshift lever on both right and left-hand controls). The MODE button lets the cyclist check battery charge, make accurate adjustments to gears or derailleur (even while pedaling) and carry out any kind of diagnostic check.

Flat Mount Disc Brake Calipers
The flat-mount Campagnolo brake callipers ensure powerful, modular braking in any situation owing to pistons measuring 22 millimetres in diameter. Brake pad return guaranteed by the magnetic system ensures that there is no friction at the time of brake lever release. A special metal plate positioned between the pad and the calliper piston, cushions the vibrations during braking.
It is indeed possible to choose the rear brake caliper with a disc measuring either 140 mm or 160 mm in diameter and to use a specific 160 mm front caliper. Additionally, work was done on the insertion of the disc in the caliper to make changing the wheel easier and faster.

Super Record EPS Front Derailleur
In-depth study by the Campagnolo technical staff for development of the new shape of the cage on the 12-speed mechanical front derailleur is now also applied to the new electronic version, guaranteeing fluid, efficient, reliable shifting. Thanks to the inner semi-cage in aluminum and the single-piece outer semi-cage in carbon fiber, the Super Record EPS front derailleur delivers maximum stiffness and efficiency when shifting.

Mechanical Components
Campagnolo Super Record cassette
The Campagnolo Super Record 12-speed cassette features thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11-speed cassette, meeting everyone’s needs with just two sprocket sets (11-29 and 11-32 teeth). The addition of the 12th sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing the cyclist to find the perfect ratio for any situation.
In addition, the closer sprockets ensure faster, quieter and more precise shifting thanks to the special tooth design and surface treatment which guarantees a longer lifetime.

Campagnolo Super Record chain
The Campagnolo Super Record chain also had to be redesigned from scratch to work with all the other 12-speed transmission components. Therefore, the first and most important objective was reducing its overall dimensions. Its width measures just 5.15 mm, thanks to the new pins which are perfectly aligned with the links’ outer surfaces.
The second objective was safeguarding its performance. This was achieved thanks to the Ultra Link system that makes the chain safe and durable, and a special treatment that guarantees extreme smoothness and precision shifting.

Notes:
Campagnolo Super Record EPS groupset is only suited for frames, that are designed for inner cable routing.
