Easy to fit and stays in place well. I think it’s strong so will be good for the job and I found it good value. Functions as expected. ### ⭐⭐⭐⭐⭐ Does what it says *by on Reviewed in the United Kingdom 29 May 2025* Fitted to a road bike aero seat post no problem however if it were a much deeper seat post like a TT/Triathlon bike then it might not fit. Used a few times now with no slipping or unwanted movement from the mount it just stays in place. 1/4 turn mount is solid with no rattling when the varia was mounted. Overall I'm glad I chose this mount. ### ⭐⭐⭐⭐ great item *by on Reviewed in the United Kingdom 2 May 2026* The item is first class my one concern is the rubber seat post mount comes in three styles and you have to take all 3 styles ie round post one, square post 1, aero post 1. rathjer than 3 of the type of seat post you need ## 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.hr/products/604736229-tusita-bike-seat-post-mount-compatible-with-garmin-varia-rtl510](https://www.desertcart.hr/products/604736229-tusita-bike-seat-post-mount-compatible-with-garmin-varia-rtl510) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-20*
