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

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.

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.

Good quality material provides strong hold for GPS.

This won't work with my vertical bar on my recumbent trike headrest, but would work with a bicycle seat post. The mount is about 22 degrees from level to compensate for angle seat post. But, seems to be a quality item. Just wished it had options for vertical rise of 90 degrees.

Just installed it but I don’t expect any issues with reliability. Great mount! Easy to install. Much better than the rubber band from the factory

Got this mount and a silicone cover from TUSITA, mount and the cover for the RTL515 = perfect! Didn't really want to trust such a nice device to an O-ring, and the case will help keep the mud off of it. And I'll connect a line to it, the case comes with a lanyard, I've seen a lot of bike lights on the paths, this is one you don't want to lose. This should come with the Varias. Do you really want to trust your radar, day in day out, to an O-ring.

This mount is so much nicer to use than the flimsy rubber band one provided with the Varia. It's easy to get the light on and off, does not weight anything at all, and is still very easy to remove for traveling/racing, or any other reason you may have for it. For the money, it does not get much better than this.

Slightly nicer build than the cheaper version you may be tempted to buy. Worth an extra dollar or two for the look/quality. Included spacers made it easy to securely fit my seat post.
