Item Description

3D Printed Mount for Garmin Varia RTL515 & Magene L508 – Fits Trek Bontrager Saddle Built-In System

Overview Keep your aero seatpost completely clean and scratch-free. This custom 3D-printed mount bolts directly into the built-in accessory threaded holes (Blendr system) located underneath compatible Trek and Bontrager saddles—including the factory saddles on the new Trek Madone Gen 8. By utilizing the factory mounting points, you eliminate the need for bulky rubber bands and seatpost clamps.

Built for the Elements Unlike standard PLA or PETG mounts that can warp, melt, or snap on hot summer rides, this mount is printed using high-performance ASA filament. ASA is exceptionally UV-resistant, weatherproof, and structural. It is engineered with optimized wall thicknesses to ensure your expensive radar stays securely locked in place, whether you are on a fast-paced group ride or grinding out a long Sunday century.
