Silca Chisela Titanium Cycling Computer - Wide Width - Garmin/Wahoo

The SILCA Chisela is not just a computer mount — it's an aerodynamic system developed in collaboration with the EF Pro Cycling Team and optimized using cutting-edge aerodynamic modeling, 3D printing, and state-of-the-art ceramic coatings. The Chisela Wide (23–40mm) fits traditional 4-bolt stems and is compatible with both Garmin and Wahoo computers (excluding Wahoo Bolt V1), positioning the computer for the cleanest possible airflow.

The unique T-Tray mounting rail — inspired by the underfloor T-channel of an F1 car — allows lights, cameras, and accessories to slide and click into place beneath the computer with no aerodynamic penalty and virtually no weight penalty. Dismount with a pull of the lever; remount with a slide and a click. The Chisela is 3D-printed in titanium with a ceramic coating finish.
