KbrotechBicycle Water Bottle Cage Holder Mount Adapter Adjustable Compatible Bike Handlebar Seatpost Fork Ultra Strong 7075 Aluminum Alloy CNC Machined

Great mounting system. Well made and extreamly strong. Just be advised that when used in the handle bar position all is well. When used in the seat post position the hinged mount must be rotated 90 degrees. In this position and absolute dead center configuration is not possible. The bracket will be off center by about 1/8 inch. I was worried this off center anomonly would look goofy. In reality its not that noticeable. I decided that the quality machining, fit and flawless finish far out weighed a minor visual alignment flaw. Thanks to this bracket two water bottles now live behind my seat making long summer rides more comfortable.

Many reviews comment on the adapter not staying in place or position, and this is very true if the supplied spacers are used, the material when compressed does not provide enough friction to keep the adapter in position or place. Hence an easy solution is to take a roll of velcro material, cut it to the width of the adapter clamp, and wrap as many times as needed to obtain about a 1/4" to 3/8" gap between the clamp at the screw securing the 2 halfs. Tighten the screw really snug, the velcro will compress providing plenty of friction between the clamp itself and whatever you are mounting to i.e seat post, handle bar, or frame tube. I used it to mount water bottle cages holding Ultimate Ears speakers (Stereo) to my recumbent trike seat frame. Speakers are mounted solidly and haven't moved at all!!!

It was easy to install on my seat post and thought that I had found a solution for a water bottle cage. On my 4th ride, the aluminum piece that attaches the mount to the seat post clamp broke and the unit fell off. Do not waste your money.

I've only put 120 miles on my bike since I mounted this bracket with two water bottles on my handlebars and it's held up without issue. Very convenient, mounted just left of my stem. It comes with two spacers so it can be mounted on a total of three different diameters handlebars. I do wish it came with a couple more spacers maybe to mount this to a seat tube.It has an option for one bracket to be mounted center or two offset to each side.This is made in china but seems well made. If it snaps off I'll be sure to post the photos!

If you already have a spare water bottle cage this holder seems on first impression to work well; just attach your cage with the included bolts and washers . The bracket is designed to fit handlebars from 22mm on up. I was concerned that it would not stay tight on my smallish bars but so far so good. The angle for the water bottle can be set as desired. I haven't had it long enough to see whether it will hold up over time. the plastic seems to be of good quality but the hinge mechanism that goes around the handlebar is lighter weight than some of its competitors and may not hold up well on bumpy roads.

This was exactly what I needed! The bracket did tend to “slip” over rough terrain, so I took the advice of another reviewer, and cut a piece from an old bike tibe to make a gasket. Cut the tube to fit the width of the bracket and long enough to wrap around the bike tube. Perfect!! The bracket is solid, and does not move at all!! (I will use the bike tire tube for gaskets in the future!).My bottle cage mounted perfectly to the bracket and works perfectly. I am pleased with this purchase and recommend it to others who need a mount with flexible placement options.

The mount is solid, no plastic parts (with the exception of the included spacers). Someone asked if it turns 360˚. Yes, but in 90˚ increments. I would have preferred for this to not be the case.Overall, I like it. My only criticism is that while it had two sizes of spacers, it didn't have the flat rubber insert for a bigger bar. The clamp fits over my bar, but it's too big to use either of the included spacers. Having a super thin spacer to put between the clamp and my handlebar would be nice. Fortunately, I had some left over from another product that I found.

Bought a Trek 20* inch bike for my niece but I dont know why it would not include those simple screws to place a bottle holder on either the lower or seat tubes. My other niece who has a 24 inch bike does not have those screw options either. Thus, after coming across this cup holder adapter, I bought one for each bike and it snuggly attached to the handle bars of both bikes. I wanted to attach it the down tube of the bikes but the tubes were too wide for this adapter. It came with the Allen key you need to attach this adapter. As long as my nieces are able to carry along a drink as they bike along, they are happy. I assume this would work well with round tube no bigger than 1 1/2 " in cirumference and I would recommend this adapter.

This worked well to relocate my water bottle onto my front rack but the rack diameter was small and had to add rubber to build it up. Wish there were a few other spacing options that allowed for a narrower application.

I use this to hold my bike lock under my bike seat. It's a hefty folding lock that is designed to mount onto a water bottle mount. The lock weighs about 3 pounds and found that the screws on this mount started loosening pretty quickly. Used blue loctite on the screws to solve that problem and this mount has been good ever since.

Bought this for my wife's bike as she likes her water bottle on her handlebars for rec riding..nicely manufactured - looks like it was machined almost.Solid and clamps well - has not moved in a dozen rides and some minor off roading / hills were involved..Would buy another if needed.

As advertised comes with inserts to adjust diameter of clamp. Would buy it again

I use this to have my bottle on my handlebars. Works great!
