Design wise its great 5/5. Cost is also 5/5 very affordable. Fits most saddles with a shorter tail. The only problem i have with it is the material it's made from which is steel. It is really heavy weighing in at a little more than 100g (roughly 1/4lbs or 3.5oz) with all the included hardware. If made out of aluminium the same product can be achieved for about 40g and weight saving is extremely important in cycling. I cant seem to find one of a similar design, but if there is one just like this made from aluminium I wouldn't hesitate to purchase it.

I love this cage mount, it saved my life since my frame has no bosses for cages. The only issue I've had with it is that the screws are cheap and one got stuck, so I had to replace them. Otherwise, great mount, and the metal is pliable, so you can bend the angle of the mount as you wish.

I bought this for my track bike. I like the look of a clean frame without a bottlecage. This was simple to install and looks great. A word of caution: not all bottlecages will work with this. Your gonna want a tight fitting cage to keep the bottle from popping out if you hit any major bumps. With that in mind, its a simple design that works very well.

I immediately knew I wanted to mount my water bottle cage to the seat rails on my bike when I noticed this was even a thing online. All I had to do was a quick search and bam! Here we are. This little awesome mount. And oh man is this thing awesome. I received it and it was neatly packed and had all of the mounting hardware.

In the package, you receive the following:
* Not compatible with i-beam type saddle. Standard dual rail type only
* Lightweight at 80 grams
* Bottle cage mounting screws included
* Not compatible with I-Beam type saddle; Standard dual rail type only

First I opened it and looked around and thought to myself "aw man there's no instructions and they are in japanese". I wasn't too bummed because it is pretty easy to figure out, but I always enjoy having instructions so I know I am properly doing it. After actually looking at the packaging, there is a little graphic on the back of it telling you how to install it. This was better than anything. It helped me get this done very quickly! To make things easier, I took my saddle off of the seat post to install it. It was a little tough trying to do it with it still attached to the seat post because I did not have a bike stand for working on it. If you want to get it done quicker, I recommend doing what I just said.

All in all, the mount is very strongly made. Stays firm in place and does not move around. A lot of people were complaining that it runs parallel to the ground, but I was able to angle mine perfectly to where it's just at an angle but a good angle and will not fall out.

If you are interested in mounting your water bottle cage to your seat post, this IS the way to go. You won't find a better deal out there and for the price of this one, you get a very quality piece of equipment.

Fits beautifully under my saddle. It's also made of steel which i really love. Im using this with an Ibera bottle cage. I have also tested this on 3 saddles: fizik, san marco, and crew. All fit perfectly. Would recommend this to anyone 10/10
