Description

Ideal for handlebars, the RAM-B-149Z-UN10U consists of a zinc-coated U-bolt base, medium length double socket arm, and the popular spring-loaded RAM X-Grip large phone holder. In addition, hardware is included to accommodate rails from .5" - 1.25" in diameter. The RAM X-Grip features an 'X' design that expands and contracts to provide a perfect fit for your device – even if it's in a case. Made of powder-coated, marine-grade aluminum, stainless steel components, and high-strength composite, this large version of the RAM X-Grip fits phones ranging from 1.75" to 4.5" in width and keeps your device completely functional and accessible. RAM ball and socket technology allows for near-infinite adjustability to achieve the ideal viewing angle – while also extending the life of your phone by providing shock and vibration damping. For outdoor applications, the RAM X-Grip includes a device tether that is recommended for added security and peace of mind. The benefit of the RAM system is the modular and highly adjustable components so you can have the exact mount you want and position it to your preference.

Strong grip, high quality
Style: Large
Works great and Holds my phone tight. I have no fear of it falling out cruising down the freeway. Nice design and high quality. If needed, will buy again in the future

Easy install and so far so good.
Style: Large
I have only had it for a couple of days. Easy to install and holds the phone pretty good with the rubber strap. Not sure if I can trust it without it. Easy to place and remove your phone. Shakes a bit and you can really see it when using the 1x camera but seems more steady when using the 0.5 camera.

U bolt spacer stinks and teather is junk
Style: Large
Mount is pretty solid with a few semi significant issues. For one they provide two u bolt sizes but only one sized spacer for said u bolt. Spacer is only in contact on the edges, not truly going around the bar. That's pretty lame and cheap and lazy. 2nd issue, as others have reported is the rubber teather is absolutely trash. They are not very flexible and one corner tore on first use. I have a glaxy s22 ultra. They will not work on larger phones. This is also unacceptable for a kit advertised as being compatible with these devices. There are aftermarket teathers available that are both more flexible and functional. ... show more

As advertised
Style: Large
Sturdy & works fine. At this price I'd like to see more mounting hardware though. It comes w/ 2 sizes of U bolts. Used the small one on my 7/8" bar. A bit of a pain to get tight enough, since the nuts are too close to the ball mount to use a ratchet. Still slips a bit. Bought an off brand quick release mount w/ a 1" ball to solve that issue. ... show more

I have a bunch of rider friends who have this same mount on their bikes and I’m happy I jumped on the bandwagon. It’s perfect! Fits perfectly, comes with two different sizes you can choose from. My Triumph street twin needed the smaller clamp. I was happy to have a choice.

Shockingly effective
Style: Large
I was getting ready to move cross country and needed a way to mount my phone/gps to my bike, and previous phone mounts have unceremoniously killed two phones before. So buying this was scary just because it LOOKS like there isn't much to it. It also didn't help that the day of my trip, the rubber arresting strap broke. I was told I didn't need it, but it left a knot in my stomach as I started heading down the road. 1000 miles and 17 hours later, and the mount was perfect. The phone (a Galaxy s20) didn't move a muscle, didn't have excessive vibration on my Harley Sportster, and it was a headache-free experience. I finally allowed myself to relax after a few hours seeing it handle the interstate like a champion. Can't recommend this enough. ... show more

Not very intuitive to install - but once on, it works really well
Style: Large
So the X shape that holds your phone can also hold smaller phones, like the pixel 3 no problem. Plenty of extra clearance to hold something even smaller. When combined with the flexible straps, this phone is not flying off your motorcycle regardless of what speed you are traveling, that's for sure. I am very surprised that something like this is so sturdy. I would look into the different types of mounting styles such as the front brake block one. I think that one is the best. This one still causes me to lower my gaze and can be dangerous if I target fixate too long. Other than that, it does a wonderful job. ... show more
