ENVE Seatpost Battery Retention Plug

What it is:
A seatpost retention plug that holds an electronic shifting system battery securely inside ENVE carbon seatposts.

Why we made it:
Electronic shifting is the gold standard and more bikes are coming equipped with these groups. Housing the battery into the seatpost is an elegant solution and a good use of space. Available in 25.4, 27.2, and 30.9/31.6mm sizes, these plugs are designed to provide excellent battery retention and interface perfectly with ENVE carbon seatposts.
