Seat Post Quarter Turn Mount Compatible with Garmin Varia RTL510 RTL515 RVR315, RearVue 820 Rearview - Fit 27.2mm 30.9mm 31.6mm Bars Seatpost

Works superbly with my Garmin radar on my seat post. Comes with useful shims and locks in securely while allowing for adjustment with a few turns of the screw.

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.

Great addition to my bike to more permanently attach my bike radar. I have 100 miles so far without any issues. Stem is standard 28.6 mm sized.

Love the deign, well built, good quality. It didn't fit with any of the provided shims on my Trek Emonda SLR 6 AXS unfortunately. Was too loose even trying all the provided shims. If only they had one extra shim a little thicker than the other two. I did notice holding it up that the angle seemed to be off a little too compared with the supplied Garmin varia mount. This mount actually put it at a slightly higher angle point the radar slightly up. Not sure if that would have an effect on the garmin radar or not.

Works well. No problems!

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.

A must have for bicycles with round seat posts. Makes connecting lights easy and they stay correctly positioned.

Perfect seat mounted. I like the design and quality

Better quality than the original Garmin quarter turn mount. My Garmin mount broke mounting it the 1st time.

Does it’s duty as a stealth AirTag mount, I have mine on the seat post.The version I have only uses a standard Allen Key and not a Torx screw to open it so as far as security goes there are places for improvement.

This would be a great way to HIDE an AIRTAG, however, this unit did not fit my seat post. Maybe there is a water bottle holder that also Hides an AIRTAG, that is also another location the thieves would not look at right away. I can hide my AIRTAG in my handle bar stem.

Excellent to pair with the radar light.
