To allow for various mounting locations, Campagnolo's EPS Power Unit Holder is available in two versions, Standard and Non-Standard.
The Standard Holder attaches the EPS Power Unit to your frame's downtube bottle mounts. The holder is slim and places the Power Unit far enough out of the way to allow a standard water bottle cage to be installed.
The Non-Standard Holder is used to mount the battery below the saddle, or under the bottom bracket EPS-specific frames. Special wire kits are required for these alternate mounting locations (sold separately).
