Banda de caja de conexiones Shimano Di2

The Shimano Di2 Junction Box Band is a straightforward replacement or spare mounting band for securing a Di2 junction box to your frame or handlebar. Designed to work with Shimano's Di2 electronic groupset components, it keeps your junction box firmly in place during rides — no movement, no rattling, no interference with shifting performance.

A small part that does exactly what it needs to. If you're building up a Di2-equipped bike or replacing a worn band on an existing setup, this is the piece that keeps your wiring tidy and your junction box where it belongs.
