The Ritchey Di2 Rubber Battery Seatpost Mount is a simple and reliable accessory for cyclists running Shimano Di2 electronic shifting systems with a seatpost-mounted battery. Designed to fit seatposts with a diameter of 27.2 mm or smaller, this rubber mount provides a secure, vibration-damping interface that keeps the Di2 battery stable and properly positioned on the bike.

Constructed from durable elastomeric rubber, the mount wraps securely around the seatpost and cradles the Di2 battery housing, helping absorb road and trail vibration that can lead to noise or wear over time. The snug fit prevents unwanted movement during riding, even on rough surfaces or under hard efforts, while also protecting the battery from scratches and abrasion. The flexible material makes installation and removal quick and easy without the need for tools.

Designed for clean and dependable integration, this seatpost mount helps keep your electronic shifting setup tidy and reliable. Its compatibility with seatposts up to 27.2 mm in diameter makes it suitable for a wide range of road, gravel, and mountain bike builds that use traditional post sizes. Whether you’re replacing a worn mount or completing a Di2 installation, this accessory supports consistent shifting performance by keeping the battery secure and protected.
