## Description

desertcart.com: TUSITA Seat Post Quarter Turn Mount Compatible with Garmin Varia RTL510 RTL515 RVR315 Rearview - Fit 27.2mm 30.9mm 31.6mm Bars Seatpost : Electronics

Review: Easy to use and well worth it - Great quality and well-built mount. I used the mount that came with the light for a few rides and was hesitant to get a fixed mount due to the angle of my seat post. But decided to give this mount a try and what a difference it made. Easy to install and holds up ride after ride. I liked it so much that I bought another one for my other bike. Highly recommend.
Review: Highly recommended, much better than the Garmin mount - My only complaint with my Garmin Varia taillight is that the included mount is a poor design, held on by a rubber band. This mount solves that problem. It fits my 27.2 seatpost perfectly and allows plenty of clearance for saddle bags. The taillight locks solidly in place. It works so well that I bought another one for my second bike.
