TUSITA Seat Rail Mount Kit Compatible with Garmin Varia RTL510 RTL515 RVR315, RearVue 820 Rearview

Exactly what I wanted. The a ability to mount my rear radar light over my saddle bag. This allows the radar to work better, I was getting false alerts before. The bracket is study being metal, the adapter plate for light also is a robust plastic, far better the the many Ali express and Temu adaptors I have bought. Don't get me wrong, I did try to find this on both sites but only found cheaper inferior versions, which is weird as this is from China. I feel the price was expensive for a no brand make, but the quality is actually good, so overall happy. Especially as I got it next day and if fulfills my specific need of not getting in the way of my saddle bag, most others will do this! I have added pic to show how it works with the saddle bag.

Very well made piece of kit, good quality and easy to fit. Feels robust and secure when placing your Garmin device.

Really good quality and easy to fit at the right position. Only those seeking something super light should be put off.

works perfectly as described and sturdy but flimsy cheap rubber band mounting doesn’t inspire confidence so purchased a separate clip on type mount for sturdiness

It does exactly what it’s supposed to do to do. Holds all Garmin products just the same or better.

This was easy to fit and holds the rear light securely. In addition, there is enough space to attach my small saddle bag under the seat.

Less than a year in screw comes off and almost lost my garmin varia

Wanted a radar mount off the seat post. Well designed, sturdy fixings. Very pleased so far

Works really with my mountain bike when I want to ride on the road and need the security of my Garmin Varia. Lots of room for my dropper seat to function. Just make sure your Varia model is listed as there are two models of the bracket.

Devo dire.... di metallo, molto robusta ,fissaggio saldo . Bel prodotto!

Worked perfectly

This mount does exactly what it’s supposed to do, but a word of caution: the metal is light and can break if you crank down on it too aggressively. I’ve seen reviews from people who snapped it during installation. That said, I had no issues at all. You just need to use common sense. This is a mount for a Garmin Varia—not something designed to hold 50 pounds. Tighten it snug, not like you’re torquing a lug nut. If you install it properly, it holds firm and feels secure. What I really like is the position it puts the Varia in. It sits perfectly for visibility and gives a clear line of sight to approaching cars. It looks clean and professional once installed. Overall, the quality is very good, and the price is excellent compared to Garmin-branded options. Just install it carefully and it performs exactly as intended.

Bought this bracket to free up space on my seat post for a saddle bag. It's really solid and way more rugged than the original Varia mount that comes with the light. If you want to use a Varia radar with a saddle bag, this is the way to go. For reference, I'm using the Vaude Race Light Luminum M here. and it fits perfectly.
