Under Saddle Bike Computer Mount for Garmin & Wahoo | Aero Track TT Triathlon Cycling Mount

Built for racers who want a clean, secure way to mount a cycling computer behind the saddle, this under-saddle computer mount brings the functionality of expensive boutique mounts into a lightweight small-batch 3D printed package. Designed for track, time trial, triathlon and road setups where cockpit space is limited or aerodynamics matter, it tucks your computer neatly beneath the saddle rails for a low-profile look while helping ensure compliance with UCI regulations in disciplines where visible computers are not allowed.

The mount is reversible to support both Garmin and Wahoo quarter-turn interfaces without needing separate hardware or adapters. An integrated lanyard loop provides extra security for bumpy tracks, travel, or trackside handling, helping prevent an expensive computer from bouncing away if the mount is damaged in a crash or impact.

Each mount is 3D printed from ASA, a UV- and heat-resistant engineering plastic better suited to outdoor use than standard PLA or PETG. Hardware is stainless steel for corrosion resistance and a clean finish. Variants are available for both standard round rails and oversized oval carbon rails.

The design prioritizes low weight, aerodynamics, clean integration, and practical durability while remaining easy to install and service with basic tools.

Features:

Reversible design supports both Garmin and Wahoo computers

Integrated lanyard retention loop

Variants available for round or oval saddle rails

ASA construction for improved UV and heat resistance

Stainless steel hardware

Low-profile aerodynamic placement beneath saddle

Compatible with many road, TT, triathlon and track saddles

Installation:

1. Select the correct version for your saddle rails (round or oval).

2. Align the mounting puck to the correct orientation for your computer.

3. Position the mount beneath the saddle rails.

4. Install the stainless hardware loosely at first and slide the mount into the desired position on the rails.

5. Tighten the hardware using a 4mm Allen key until secure. Do not overtighten, especially on carbon saddle rails.

6. If desired, connect a lanyard through the integrated retention loop.

7. Attach your computer using the standard quarter-turn interface. The lanyard can be wrapped around the computer after installation to help keep it out of the wind.

Notes:

This is a small-batch item produced on a consumer-grade 3D printer using ASA filament. Minor surface variation or layer texture may be visible.

Due to variation between saddle rail shapes and saddle shell designs, fitment may vary slightly between models.
