ENVE Composites Seatpost Battery Plug

While it is designed specifically for ENVE carbon seatposts, it may fit other carbon seatposts with similar internal diameters. However, we recommend verifying your seatpost's internal diameter and wall thickness to ensure a secure, rattle-free fit.

You should select the plug size that corresponds to your seatpost's diameter. The available options are 25.4mm, 27.2mm, and a combined 30.9/31.6mm size, which covers the most common seatpost standards.

Yes, the plug is engineered to provide a snug, secure fit that holds the electronic shifting battery firmly in place. This prevents movement and annoying rattles while you are riding over rough terrain.

The plug is designed to house standard cylindrical electronic shifting batteries, such as the Shimano Di2 internal battery. It is best to confirm your specific battery dimensions against the plug's internal cavity if you are using a non-standard system.

Installation is straightforward and can be done at home with basic tools. You simply slide the battery into the plug and insert the assembly into your seatpost, ensuring it is positioned correctly before tightening your seatpost hardware.
