Performance The Airstryke II is intended to allow riders to add aerobars to their road or adventure bike without sacrificing the ability to hold the bars close to the stem. The comfortable grip angle and smoothly curved armrest offer a relaxed position for long days in the saddle. Fit Data - Armrest Offset: -85mm to 17.5mm in 7.5mm steps - Armrest Width: 131mm to 298mm in 18.5mm steps - Armrest Stack: 40mm Origin As one of the most popular model in the history of aerobars it seemed appropriate to update the much loved Airstryke with our new generation fit range and comfort focused armrest. We didn't want to change the elements that have made the bar so successful and the changes made just enhance the adjustability and comfort. - Bracket: L2 Flip-Up - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Ergo Armrest - Armrest Stack: 40mm - Reach: -85mm to 17.5mm in 7.5mm steps - Extension Adjustment: 150mm (center of basebar - end) - Armrest Width: 155mm - 203mm - Weight: 592g

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.

Campagnolo's Record EPS V2 Power Unit is the reliable brain of Campy's electronic shifting. In order to keep your bike looking sleek, the mounting options allow it to sit inside your bike's frame. The 3-cell, 12-volt Lithium-ion battery 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). For example, if you're cross-chained, the system immediately senses it and moves the front derailleur ever so slightly to avoid chain rub. Plus, the one-piece, ultrasonically-sealed unit is impervious to water or road vibration.
