SIGMA AERO BUTLER GPS – aluminium bike computer mount for aero handlebars

The SIGMA AERO BUTLER GPS is a lightweight and durable mount designed to install compatible SIGMA ROX GPS bike computers directly on aerodynamic aero handlebars with a Direct Mount system. Made of aluminium, it weighs just 44 g and helps maintain a clean, organised cockpit on road and gravel bikes.

Thanks to its adjustable mounting holes, the AERO BUTLER GPS can be adapted to different hole spacings on the handlebar, providing a stable and secure computer mount.
