All CeramicSpeed Bearings are hand-built in Denmark. Super-smooth CeramicSpeed grade 3 Silicone Nitride balls are matched (within microns) with hardened steel raceways that feature an ultra-smooth polished groove. The balls are held in place by a reinforced polyamide cage. Every bearing is optimized with a low-viscosity CeramicSpeed All Round Grease to minimize friction and increase bearing life. Non-contact seals complete the bearings, keeping dirt and moisture out. CeramicSpeed Bearings can be used for any cycling discipline: Road, TT, Tri, Track, Cross, and MTB. The benefits are super low friction, better power transfer, and increased bearing life. During the building process, we check each bearing four times by hand to ensure that all parts are matched perfectly. CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel bearings normally used in the bicycle industry. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads, and are 100% smoother. - Inner Diameter: 17mm - Outer Diameter: 30mm - Width: 7mm

Campagnolo's Record EPS V2 Interface Unit is like a translator, the vital 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.

The Subsonic/Race/35a aerobar combines the low stack Subsonic bracket with the arm-hugging Race armrest to offer an industry-leading fit range oriented towards low, narrow positions. The 35a extension offers a comfortable 35 degree angle with a 80mm rise. This is the only low stack clip-on in the market that maintains the pad-to-grip angle as the bar is stacked up Subsonic is not just another aerobar bracket. It brings our next-generation fit range to a low stack bracket design. This allows the bar to use our riser kits to increase the stack without changing the relationship between the armrest and the grips. The Race armrest has been designed to tightly cup the riders arms – facilitating a narrow position and increasing control at speed. Performance - The Subsonic/Race is designed to achieve a lower stack height than standard aerobars, without the added frontal area of a below-the-basebar extension clamping system. This improves aerodynamics and the fit range. Fit Data - Armrest offset: -85mm to -17.5mm in 7.5mm steps - Armrest Width: 142mm to 272mm in 18.5mm steps (with Extensions at 100mm) - Armrest Stack: The minimum is 40mm and the bracket is compatible with our existing risers which add up to 70mm of stack in 5mm increments. - The extension rotation can be easily adjusted using the shaft bolt. There is a 40mm range of extension length adjustment once the extensions have been cut. There are 80 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1200 possible configurations. As a clip on bar it is also possible to adjust the extension width and tilt easily. This is the most adjustable low stack clip-on on the market. Origin Story After we released the Supersonic (J5) as a premium bracket with market leading fit options and verstility we wanted to bring the same kind of options to teh rest of our range of brackets and thus aerobars. Where our supersonic and Sonic brackets have a minimum stack of around 60mm, like most of the popular aerobars - we wanted the Subsonic to offer a substantially lower position. This helps the segment of the market who struggle to get into their ideal position with modern bike frames. And it was vital that we include stack height adjustment without altering the pad grip relationship - so our riders have the ability to fine-tune every aspect of their setup. The Race armrest shares the flippable design of the rest of our new generation armrests. By swapping sides or rotating the armrest, smaller increments of movement are achieved - making it simple to fine-tune a rider's position or match the position from their previous aerobar or bike. Additionally, there are two thicknesses of cushion available to ensure a snug fit for different sized arms. Who is it for - This bar is perfect for riders who wish to achieve lower positions than are possible with standard aerobar designs. Unlike other low stack bars, it allows fine-tuning of the stack height so the rider is not limited to only one armpad height. With the Race armrests fitted, it is tailored towards riders who intend to be low and narrow to punch the smallest possible hole through the wind. - Bracket: Subsonic - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Race / 5mm Pads - Extension Length: 350mm - Width: 142mm to 272mm - Weight: 590g

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).

CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel bearings normally used in the bicycle industry. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads, and are 100% smoother. - Inner Diameter: 17mm - Outer Diameter: 26mm - Width: 5mm
