  • Works Wonderful
Size: Varia RTL510 RTL515 RVR315 Rearview Mount
Much better that OEM mount and leaves room for an under-seat pouch. Very solid and east to install, light/radar goes on and off very easily.

  • Solid inexpensive option
Size: Varia RCT715 Mount
Great deal and works as expected. I would recommend using grease or loctite to prevent threads from seizing or rusting.

  • Easy install, sturdy and fits well under your saddle
Size: Varia RTL510 RTL515 RVR315 Rearview Mount
Well built, easy to install and seems very sturdy. The fit on my saddle worked well and is adjustable if you need to move it around. After tighting the screws under the saddle it is extremely stable. The adjustable "arm" also is easy to move around and make sure the light will be seen clearly from behing and that the radar will pickup the approaching traffic. I ... show more

  • Great mount just secure the screws that hold it
Size: Varia RTL510 RTL515 RVR315 Rearview Mount

  • As well made as, and cheaper than, Garmin version
Size: Varia RTL510 RTL515 RVR315 Rearview Mount
Quality seems very good. I'd recently bought and installed the Garmin version of this to replace the cheesy, insecure seatpost mount Garmin supplies with their Varia 515 rear radar/light. This Tusita seems just as high quality as the Garmin seat mount, and this is less expensive. I added a curved 3" aluminum alloy extender to position my radar light up and back on my touring bike -- to give lots of height clearance over my rack top bag. I also bought a silicone cover with a leash/tether for my 515, since Garmin dropped the ball on providing a tether attachment point on their 515. ... show more

  • Didn't get to use.
Size: Varia RTL510 RTL515 RVR315 Rearview Mount
Product snapped while tightning during install. May have been at a stress point that caused the fracture. How do I get a replacement upper rail mount?
