3.0 out of 5 stars does what it says on the tin 4 Jan 2014
Verified Purchase
good item, my only concern is that it should have some sort or rubber or plastic grommets to protect the handle bars from getting scratched or scuffed, i took it off to put it on my other bike and it left a nasty scuff mark on the handlebar

2.0 out of 5 stars Not complete 27 Oct 2013
By Buck R
Verified Purchase
I researched this item as I needed a ram mount that would work for smaller diameter bars (13mm). When the adapter is included with the second smaller "U" bolt this will do that.
Unfortunately this item, although advertised as having these items did not arrive with them.
The packaging was sealed so it either was:-
a. missing from the manufacturer or:
b. Not included when sent out or:
c. The listing was misleading.

The seller (Anymount UK), tells me " it seems very unfair to blame a retailer for a fault which obviously occurred at manufacture..??" It is obviously too much trouble for them to look into a clear plastic wrapper to check.

Returned for refund.

Amazon customer services again were faultless.

4.0 out of 5 stars Very tight on a 1.24" tube 14 Sep 2013
Verified Purchase
I fitted this to a roll cage on a Caterham which is 1.25mm plus the thickness of the powder coat and it was very tight. Impossible to fix, even after stretching the u bracket, without damaging the powder coat, which is a shame,

4.0 out of 5 stars Solid Mount on Trek DS 8.5 Bicycle 12 July 2012
By R. Knowlton - Published on Amazon.com
Verified Purchase
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 blend 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 ball
2 black U-bolts--a smaller 1" width one and a larger 1.5" width
2 nuts with nylon friction inserts
2 rubber nubs to cover the U-bolt ends
1 plastic adapter insert to narrow the U-bolt down for use on handlebars as small as 1/2" in diameter

Be 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.

5.0 out of 5 stars You cannot go wrong with RAM when attaching items to your motorcycle 31 July 2013
By Donna M. Miller - Published on Amazon.com
Verified Purchase
RAM products are as magic as duct-tape or Velcro, you can do so much with them.The product is as discussed on all the websites that illustrate it; however, what the picture does not show is another piece that is essential to the mounting of the bracket to the handlebar of a motorcycle. In order to prevent the attachment from slipping on the handlebar from the position it is mounted in, there must be a non-slip material placed between the horseshoe metal bracket and the handlebar. What is not pictured is the piece that "is" provided with this unit that slips between the metal bracket and handlebar on the underside of the handlebar. Without it you would need at least a piece of sheet rubber.

4.0 out of 5 stars RAM Mount with U bolt base 24 Aug 2011
By L. Justice - Published on Amazon.com
Verified Purchase
I am using the RAM Universal Finger Grip Holder with RAM's mounting hardware to hold an iPhone 4G on street bike handle bars including the RAM Mount with U bolt. It grips the phone well and I have not fear of it falling out. I do have phone cover and used the RAM supplied rubber finger covers. The RAM products are well made and seem very durable. Only problem found is the handlebar mount is hard ABS type plastic and will spin on the bar. I used a strip of rubber under it and that helped I am very satisfied.

Not much to say... if you use any RAM Mount stuff on a motorcycle you need at least one of these on each motorcycle. Really nothing to go wrong, very sturdy.

4.0 out of 5 stars Works Well 21 May 2012
By Paul - Published on Amazon.com
Verified Purchase
I have this mounted on a .5" mirror stem on a scooter, and grips very securely using the included plastic spacer not shown on pictures. I added a strip of rubber to prevent scratches on the stem. Did 420+ miles this weekend on highway and off-highway riding through potholes and other terrain that will make you shake, and this mount did its job with shining colors.

Minus one star because of extra material on one of the holes that I needed to file off, for the u-bolt to fit through it. Nothing major, but it would've been nice not to bother shaving off some metal! Hope it doesn't rust fast.
