Bike taillight Mounts, Bicycle Saddle Support Seatpost Mount Tail Light Holder for Garmin Varia Rearview Radar RTL510, RTL515 and TL300...

This is a solid mount for the Garmin Varia radar system, and does a good job holding it in place. The mount installs and adjusts easily with a 3mm hex wrench. The simplest installation method without risking losing parts is to loosen the screws on the bar to the point it will fit around the saddle rails, and then simply tighten them, back and forth, until the mount is secure. Adjusting the angle of the radar is simple with the same tool. This mount puts the Varia in a very visible location, but there are some potential drawbacks, depending on your cycling setup. The main drawback is that this will make it almost impossible to ride with a saddlebag. If you carry tools/tube/plugs/CO2 elsewhere, it's not a big deal. If you need that space for the saddlebag, this will not be as helpful. Another potential drawback will depend on your saddle quality - the mount is pure aluminum, with no provision to cushion the mount against the saddle rails. If you have steel, it will hardly matter, but if you have carbon or maybe even aluminum, you could potentially leave marks or even damage your saddle rails. A simple improvement would be rubberizing the contact point with the saddle rail, as this would reduce the clamping force necessary for a secure fit. Overall I really like this mount - as long as you have the space on your bike, and you're careful with your saddle rails, I think you'll find it to be a great spot for your Varia radar, too!

THe garmin fits and it the mount fits snug to the bike saddle.

very good product and fits perfectly and strongly onto the seat rails

This mount is simply fabulous especially over the stock varia mounts. This mounts on the seats frame and provides a far nicer option for mounting than the varia straps. It is perfectly milled and fit my many bicycles. What I like best about this is that I can utilize this on bicycles where the seat post tube would otherwise cause the radar to misfire due to my tire or where it may have been in the way due to a saddle bag. The mount installs in minutes and the varia attaches firmly to it. Overall it's a fantastic value and I will be purchasing more of these in the near future to keep on my other bicycles.
