Campagnolo's EPS Power Unit is the reliable brain of electronic shifting. Inside sits a 3-cell, 12-volt Lithium-ion battery that delivers up to 1,200 miles on a single charge. It also houses the electronics necessary to deliver pinpoint shifting precision to the front and rear derailleur mechanisms (sold separately). If you're cross-chained, the system immediately senses it and sends a message to the front derailleur to move ever so slightly to avoid chain rub. Plus, the one-piece, ultrasonically-sealed unit is impervious to water or road vibration.

The EPS Power Unit is the systems source of power as well as the "brain" of the system, responsible for managing the battery pack, enabling and monitoring the front and rear derailleurs and communicating with the Interface Unit. - Weathertight, o-ring sealed connectors - Lithium Ion battery duration: 500km/month - 1500km, 1000km/month - 1800km, 2000km/month - 2000km - Water proof to 1m for 30 minutes (IP67 Rated) - Operational temperature: -4F to 140F - Charging temperature: 32F to 113F - 17mm diameter for easy seat post installation - Battery charges through the Interface Unit - Compatible only with the Super Record/Record V3 Power Unit

In conjunction with the EPS Power Unit, the Interface is the "thinking" center of EPS and is responsible for on board diagnostics, managing settings, converting analog signal from Ergo Levers to digital and sending it on to the Power Unit maintaining a dialogue with the Power Unit. - New shape with LED indicators on 3 sides - Battery charges through the Interface Unit, no more need to drill a charging port hole in the bicycle frame - Contains a wireless module allowing for connection to PCs, smartphones, tablets, etc., through ANT+ and Bluetooth Low Energy (BLE). Requires the use of Android 4.3 or newer, or iOS 8 or newer - Only compatible with Campagnolo Super Record and Record V3 Power Unit - Waterproof to 1m for 30 minutes (IP67 Rated) - Weathertight, o-ring sealed connectors - See PDF for complete details on the V3 app and customization

Campagnolo's EPS Interface Unit is like a translator, the vital but often overlooked piece of the electronic shifting puzzle. Mounted to the brake cable or the handlebar, it processes the data churned out by the EPS Power Unit (sold separately) and communicates it to you via an easy-to-read colored LED. Plus, it plays the critical role of converting every analog shift you send its way into a digital format so the system can work as a cohesive whole. There's also an easy-to-read LED battery gauge so you know when it's time to recharge the system. And don't mind the weather, as it's totally waterproof.

MisMatch adapters allow users to mount Shimano & SRAM brakes and shifters on one clamp. MisMatch Adapter 1.0/1.1 attaches SRAM shifters to Shimano I-Spec-A or I-Spec-B brake lever clamps.
