No matter if you're on riding tarmac, gravel, or rough trails, with model-specific fits and universal options, Framesandgear® delivers precision without compromise.

Compatible Bike Models

We offer Garmin Varia seatpost mounts tailored for popular performance bikes and advanced frame designs. Among others, we provide dedicated solutions for:

• Canyon: Known for sleek aero integration and aggressive geometry, Canyon bikes like the Aeroad benefit from our mounts that match their proprietary seatpost shapes. Our Varia mounts sit flush, providing a vibration-free hold that aligns with the aerodynamic profile of the frame.
• Cervélo: Built for speed and precision, Cervélo’s road and triathlon bikes demand secure mounting solutions that do not compromise aesthetics or airflow. Our mounts are shaped to fit Cervélo seatposts accurately, giving you both aerodynamic consistency and reliable radar/light positioning.
• Giant: As one of the largest bike manufacturers in the world, Giant offers a wide range of road and endurance bikes with varying seatpost designs. Garmin Varia mounts include universal and fit-specific options for Giant setups, ensuring optimal alignment and tool-free daily use.
• Specialized: From the race-ready Tarmac SL7 and SL8 to all-road builds, specialized frames often feature proprietary seatposts. Framesandgear® offers model-specific Garmin Varia mounts that precisely match these shapes, offering riders a bolt-on solution with perfect positioning, no adapters required.

Each mount is shaped to match the unique seatpost profile for a flush, integrated fit.

Engineered for Strength, Weight, and Durability

Our products are crafted from high-performance HP Nylon PA12, an industrial-grade thermoplastic that offers the ideal balance of rigidity, resilience, and lightweight construction. Each model is CNC-manufactured for tight tolerances and weighs just 31–34 grams, making it virtually unnoticeable while riding your bike but unmatched in strength. The result? A sleek, robust mount that stands up to daily use, road vibration, and the occasional harsh ride.

Secure, Low-Profile Design

Every Framesandgear® Varia seatpost mount is built for stability, security, and stealth. The bolt-on design keeps your Garmin device locked in place, even across cobbles or technical descents, while the low-profile aesthetic keeps your setup clean and aerodynamic.
Several models include a reversible insert, letting you fine-tune the orientation of your Varia radar for optimal light output and rearward radar detection. This is simply smart integration that enhances your safety and setup.

Fits the Garmin Varia RTL515 and RTL516

Framesandgear® seatpost mounts are purpose-built for seamless integration with the Garmin Varia RTL515 and RTL516 rear radar and light systems. The mounting interface is engineered for precise alignment and optimal device angle, maximizing visibility, radar performance, and road awareness.
Quick access for removal or charging is built into the design, making everyday use simple and efficient. As the Garmin Varia becomes an important tool for rider safety, these mounts ensure it performs exactly as intended—secure, stable, and ready for every ride.

Designed for Every Discipline

From fast-paced road cycling to rugged gravel adventures and singletrack sessions, Garmin Varia seatpost mounts from Framesandgear® are trusted by riders across all disciplines. Their rugged construction and vibration-resistant fit make them a perfect match for off-road riders, while their aerodynamic profile appeals to road cyclists seeking performance without bulk.

How to Install a Garmin Varia Seatpost Mount

Installation is fast, clean, and secure. Here’s how to get started on setting up your Garmin Varia mount:

1. Prepare the Seatpost and Mount

Clean the seatpost area to remove dirt and debris.If using a universal mount, select the correct rubber pad or shim for your seatpost diameter:

• 27–28.6 mm: Use the thicker pad.
• 30.4–31 mm: Use the thinner pad.
• 31–31.8 mm: No pad needed.

2. Position the Mount

• Place the mount (and pad, if required) against the seatpost.
• For model-specific mounts (e.g., Specialized SL7, Colnago, Factor), align the mount with the seatpost profile for a flush fit.

3. Attach the Mount

• Insert the fitting bolts through the mount and into the seatpost (or clamp around the post, depending on the design).
• Tighten the bolts evenly.
• For universal mounts, ensure the contours of the rubber pad align with the grooves inside the mount.

4. Torque the Bolts

• Tighten the bolts until the mount is secure and does not move.
• Recommended torque: Up to 0.3 Nm (3 lbf-in) for clamp-style mounts, or as specified by the manufacturer.
• For model-specific bolt-on mounts, use a torque wrench and follow the included instructions for your bike and mount.

5. Install the Garmin Varia Device

• Align the tabs on the back of the Varia device with the notches on the mount.
• Press down slightly and turn the device clockwise until it locks into place.

6. Final Checks

Ensure the mount and device are stable and do not rattle.
Confirm the device is facing directly backwards and is perpendicular to the road for optimal radar and light performance.
Periodically check the tightness of the bolts, especially after your first few rides.
