EPS shifting is only as clean as the wiring behind it, and that's exactly what this kit handles — the connection between the power unit and derailleur that most riders never think about until it's routed wrong. The AC12-CAADSPEPS gives you every cable and fitting needed to mount the EPS power unit properly and keep shift signal transmission consistent, whatever position you've chosen for it.

Three mounting positions, one clean install:

• Under the bottle cage — accessible for quick checks, though it costs you a cage mount
• Under the chainstay — keeps things tucked away and out of sightlines, a common choice on builds prioritizing aesthetics
• Under the saddle — the most discreet option, favoured when seatpost design allows for it

None of these positions changes how the system performs — the kit is built to transmit power and shift signal reliably regardless of where the unit ends up, so the choice comes down to your frame's routing and what you want visible.

What's actually in the box:

• Full cable set specific to Super Record EPS, matched connector-to-connector rather than needing splicing or adapters
• Designed for straightforward installation — this is a kit built to go in clean the first time, not one that needs repeated trial fits

If you're building or servicing a full EPS setup, this is the kind of detail that's easy to overlook until a shift lags or drops out entirely — worth having correct from the start. Check our Electronic components range for junction boxes and satellite shifters to complete the install, or Batteries for EPS power units and spares.
