12 speed. 5 pieces (Super Record EPS Ergopower carbon levers, EPS front derailleur, EPS rear derailleur, V4 Interface External Charging Interface - Internal Handlebar Interface - select Optional Substitution).
Optional: Battery Charger and Battery Charger Cord Outlet.
The new Power Unit, its fairly slender shape making it compatible with all the seat posts on the market, is quick to fit with one of the two different adaptors, the choice of which will depend on the size of the post. Even longer life for this, the sector’s leading battery, thanks to a 10% increase in its charge capacity, meaning it rarely needs charging.
The New V4 interface incorporates the lions share of the innovation placed in this award and race-winning electronic transmission.
All communication between the Ergopower control levers and the front and rear derailleur components becomes a specific action thanks to the new interface. The V4 version not only receives the electronic impulses and sends them to the front and rear derailleurs; thanks to its two internal aerials, with both Bluetooth Low Energy and ANT +, it can also communicate in real time with a vast range of external devices, ranging from phones to bike computers, through to any other electronic device used by the cyclist.
Technology:
- DTI: Digital Tech Intelligence
- On Board Diagnostic
- Waterproof - IP 67
Enclosed and protected in the Power Unit and interface, "Digital Tech Intelligence" transmits, receives and processes data thousands of times a second.
An electronic brain which instantaneously synchronizes all the functions requested by the rider. With just a simple click of the controls, D.T.I transmits the corresponding signal instantly, accurately and reliably to the rear or front derailleur, for levels of performance and control feel never experienced before with a conventional drivetrain.
But as well as all this, the D.T.I. system also monitors the entire drivetrain and each of its components, continuously checking battery level and functionality, and checking that the rear and front derailleur are working correctly.
- Zero Settings
The procedures to reset the rear derailleur and derailleur to zero are essential for the system to function.
These procedures allow the system to learn the reference positions of the chain on the sprockets and chainrings, which will be used to calculate the positions that need to be used in all operating conditions.
During the resetting to zero phase the movements of the rear derailleur and derailleur occur continuously, and not through set movements as during adjustment, and they depend on the pressure time of levers 2 and 3.
The position can be changed by even just a hundredth.
