Garmin Varia Radar Seat Rail Mount

Great mount if you need flexibility to adjust the angle of your radar/taillight. Easy to install and remove when placing your light/radar on a seat bag or rear rack.

Have been using a much cheaper (about $15) rail mount made out of "reinforced nylon." Worked great for about 3 years until it didn't, and the mount broke off and I had to go back and retrieve my Varia from the ground. Road bike, so wouldn't think nearly the maximum stress the part would see.Just got this as a replacement. All metal part. Three times the price, but worth it to me (assumes it holds up as well as I expect it to). Fits my bike well, just able to install it and my saddle bag without any additional parts.

Great way to protect an expensive piece of cycling equipment. I went for years without this case and I am glad I have it now. The Varia never fell off, I did drop it a few times and the case would have helped. I like that I can put the Varia on my bicycle and then put the bike on my rack and not worry that the Varia would fall off while I am driving.

I always hated how the varia mount looked on my seatpost. I have tried all sorts of other cleaner 3D printed options but they never worked well. This one is rock solid and it looks very neat tucked up under my saddle! All the parts are very high quality and I haven’t had even a hint of slippage so far.I see another reviewer who returned this item because (in their defense) the description does say “for alloy rails” in the description. I have had no issues after a hundred or so miles on my carbon rails. Carbon is not as fragile as people make it out to be as long as you work within the limits of its material properties. I put some carbon grit paste on the clamping surfaces and have it torqued to ~4Nm and there is zero slippage. 4Nm is well under what my rails are rated for, my seat clamp is torqued almost twice as much, and those also bear my full body weight. I am not worried about an item as light as a varia clamped to such a low torque spec. Obviously proceed with whatever caution you wish, but I think these are fine for carbon rails!

This item is solidly built and functions as advertised. The camera mounts very securely. I still manage to get a bag under the seat when I go on long rides (see picture).

At the moment, Garmin decided we need a lever lock handle to keep the RCT715 mounted. Guess they feel the extra weight under certain circumstances can defeat the quarter turn system. So rather than keep a common solution so you can use older units with the quarter mount solution (RCT515) they expect you to ditch your old equipment or come up with a homegrown solution for either seat mount or seat post mount. Looking at seat rail mount, without a longer extension, this will not fit past most bags. If I was reviewing on this, a 1 star would be in order. But there is a silver lining here. The kit gives you a female quarter turn to go pro style friction mount as well as a lock lever mount to go pro style friction mount. Obviously they feel the go pro style friction mount is strong enough for both units in this chain. So if you, like me, have many bikes with a quarter turn female mount on your seat post, you can buy this kit and buy a separate male quarter turn to go pro mount and simply put the latter into your seat post mount and have a common interface. Good enough for Garmin on their seat rail mount so good enough for seat post mount (may run some extra electrical tape over the rubber stretch piece). Just in case, I put a loop style go pro safety wrist strap behind the lock lever and wrap it around the seat rail (similar to provided in RCT515 in case something goes wrong). No problems so far but no crazy terrain yet either. So if you want to repurpose this it is an over priced but good piece of kit

I was bummed that I didn't have enough clearance mounting it to the seat post of my bike with the mount the varia comes with. My bike has a dropper post and that's why I couldn't.This mount works perfect. Easy to install...a little on the more expensive side, but I know it's not going to break or come off mid ride

After buying a few under saddle mounts, I finally decided to splurge and buy this. At the time it was 10.00 off. I was not disappointed. Excellent quality and sturdy, solid mount. As this is for my gravel bike, I will need a stiff mount for the washboard roads. 100% Worth the extra money.
