Overall I'm glad I chose this mount. ### ⭐⭐⭐⭐ Better than the supplied Garmin version *by M***Y on 21 July 2024* I just purchased the Garmin radar and have read the supplied mount can come off ejecting the device, so I got this third party version. Good quality and installs in seconds with two rubber band mounting straps in different sizes. ## Frequently Bought Together - TUSITA Bike Seat Post Mount Compatible with Garmin Varia RTL510 RTL515 RVR315, Rearview Radar - Round,D Shaped,Aero Seat Post Compatibility - Garmin 010-02376-00 Varia RTL515, Cycling Rearview Radar with Tail Light, Visual and Audible Alerts for Vehicles Up to 153 Yards Away - TUSITA Seat Post Quarter Turn Mount Compatible with Garmin Varia RTL510 RTL515 RVR315 Rearview - Fit 27.2mm 30.9mm 31.6mm Bars Seatpost --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/604736229-bike-seat-post-mount-compatible-with-garmin-varia-rtl510-rtl515](https://www.desertcart.vu/products/604736229-bike-seat-post-mount-compatible-with-garmin-varia-rtl510-rtl515) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
