RAM Mounts Handlebar U-Bolt Base for Rails 0.5" to 1.25" Diameter RAM-B-231ZU with 1" Ball - Perfect for Motorcycle, Bike, and ATV Accessories

Easy to install. Very sturdy. Fast shipping.fit on the bares with the small spacer . Seem to be solidWorks great very sturdy.I have two of these:One is used as a kickstand extension on my adv bike and has been through a decent amount of torture and never once even shifted.The other is used as a mount for my GPS both the adv bike and a 450 trail bike. The going got rough enough that the ball of the x grip sheared off the back of the gps holder but the mount (and mount arm) didn’t budge.Don’t hesitate to get one if you’re on the fence, and do NOT buy the generic version. I did, sent it back asap as it isn’t anywhere near as durable.Comes with clamp size to work well with 1 1/4" bars.ram mounts are always top quality. nothing new there. it works perfectly, parts were of highest quality. you can see i added some electrical heat shrink onto the u-bolt just so i wouldnt marr the finish on my handlebars, not that i think i would have, but better safe than sorry.Pricey, but well worth the hype. Paired with an adapter and a phone holder, this is a rock solid solution to other crappy phone holders. My phone doesn't vibrate or move at all, and it's super easy to remove when I'm done with my ride. The bracket mounts easily with a couple of long screws and nuts. Just make sure you have the real estate on your handlebars to mount. Otherwise, I'm sure you can go with a brake reservoir mount or something else from Ram.I'm using three of these RAM U-bolt mounts on a Trek DS 8.5 hybrid bicycle. Although the 31.8mm diameter handlebars have a tapered diamater rather than a fixed diameter, I was able to tighten this mount down securely with no problem by using the smaller of the two U-bolts. The larger 1.5" U-bolt also fit nicely over the fattest 31.8mm section of the handlebars. The V notch on the bottom of the mount combined with the U-bolt allows easy tightening against a round surface with increasing diamater. I use it to hold a Garmin Oregon 450, a Samsung Galaxy Player WiFi 5.0, and a flashlight/headlight. I appreciate that the U-bolts I received in this kit are painted black: The black hardware blends better with my black handlebars.One of my favorite features of RAM products in the ball-and-socket joint. Once you tighten it down, it stays put. However, there's still a little bit of flex in the rubber balls so that whole setup absorbs some shock. I appreciate that on my mountain bike.The kit includes (see additional uploaded picture):The aluminum mount with 1" rubber ball2 black U-bolts--a smaller 1" width one and a larger 1.5" width2 nuts with nylon friction inserts2 rubber nubs to cover the U-bolt ends1 plastic adapter insert to narrow the U-bolt down for use on handlebars as small as 1/2" in diameterBe careful with part numbers. RAM-B-231Z items seem to have multiple configurations on RAM's website. Some hardware is zinc coated, some is stainless steel, and some is black powder coated. I ordered RAM-B-231ZU from Amazon retailer GPSCheap and received the parts as indicated above. I ordered another RAM-B-231ZU from GPSCity and received the zinc coated 1" U-bolt only.The rubber nubs were too loose to use in my application, partly because their inner diameter is too large and partly because I didn't have enough of the U-bolts exposed for them to be very useful or secure. Also, the kit does not come with washers (-1 star) and you'll likely scratch the mount with the nuts as you tighten if you don't add your own washers. I added washers in order to protect the mount. Be cautious when installing: If you're metal against metal, you may cause some scratching with the U-bolt as you position it.A good, solid piece of kit that feels well made and of substantial weight (which is quite reassuring). Easy to fit although my motorbike doesn't have full width handlebars so was a bit different but got it on and it's well secured. Only purchased and fitted a short while ago but have been out for a few runs with no issues and I'm really pleased with it and would definitely recommend.RAM Mounts are Ooozing and this one is the same well thought out useful item that mounted nicely on the accessory bar behind the screen of my 2019 cb500x so i can have my Ram phone mount sitting in full view for Gps navigationOn the whole Ram stuff is expensive but I haven't found anything that comes close in convenience and sturdiness.Well constructed heavy duty fitted perfect on handlebars. Used on harley davidson softail no vibration issues with the whole ram mount system the phone doesn't shake at all. Worth every penny so happy i went for the Ram system.Useful and very sturdy
