When you carry your water bottle behind your saddle, it reduces air resistance. It is the logical choice for triathlon and time-trials, where aerodynamics is the key. The angle and height of the clamp are adjustable. You can have one or two bottle cages mounted.

Keeps the bike as aero a possible

Rated 4 out of 5 by Feeq15 Could have been better
When fit on to the saddle rail, together with the adjustable position of the bottle cage, it gives the aerodynamic look. Would have given a higher rating if it comes with a bottle cage bolts.
Still, nice & good buy.

well this piece comes with 3 sets of parallel holes that give us a chance to choose where you want your bottle cage to be mounted on. you can mount 2 cage side (L and R) then center with a portable air pumps. usefull and save spaces.

Rated 3 out of 5 by AloyDG Not too bad BUT design concept have much room for improvement
I like the idea of flexibility. You can put 1 bottle cage in the middle or 2 side by side. I just dont like the way this thing installs.
Basically there are 2 parts to this seat clamp. The clamp part (A) to your seat rails and the cage holder part (B) that connects to the clamp part (A)
There are 3 bolts ; 2pcs of the same size bolts to fasten the clamp (A) to your seat rails and 1pc for the hinge to hold the cage part (B).
All bolts use the same size allen hex key to tighten.
For Part A. you need 2 of those washers for both these bolts but you dont need the nuts to tighten the metal clamp to the rails of your seat as the metal already has threads that allow your 2 bolts to do the job.
Screw it tight with the allen key and you should have a very good grip there but dont do it tightly yet.
Next, put that round piece of tube in between the hinge of Part B and use the 2 big washers that came with it, screw in the bolt with 1 washer and put the other washer on the other side. You will need the nut that came with the package and a plier or a wrench to hold that nut while you tighten the bolt. Do not tighten yet as you want it to swivel at an angle and position everything before you tighten.
You will notice that all 3 bolts uses allen key but because of the nut, you need a pair of pliers or a wrench which is quite an inconvenient. While cycling on the road you do not want to be carrying unnecessary tools with you and if that hinge is loose, good luck.
Next take your bottle cage and USE YOUR OWN CAGE BOLTS to tighten the cage to PART B. Yes the package does not come with these bolts. YOU HAVE TO USE YOUR OWN. If you have 2 bottle cage that you want to install, then you need 4 of your own bolts.
Using your own bolts, screw thru and use that square nuts that came with the package.
DO NOT USE THE WASHER on the side where the square nut is suppose to lie in. This is becos the indent where the square should be is just nice to accomomdate that nut. By using a washer, you elevate the nut and it will not hold down when you are tightening your cage.
Once all that is done screw and tighten Part A to your seat rails. Angle Part B in such a way that you can have easy access for you to tighten the clamp.
Now that the clamp is tighten, swivel and angle Part B to your liking and then tighten it.
Your bottle cage holder or holders should always be tighten to Part B.
To unloosen your clamp you need to unloosen Part B.
Overall the job is really fiddly and if you have big fingers, you will find yourself dropping the bolts and the washers often but once you get it in place, it becomes easier.
To buy it or not, well, do you find yourself needing 2 bottles? Are there better alternatives?
For a price like this, it isnt value for money considering the quality of the parts, the way this needs to be installed, the hassles. I do believe there is much much more room for improving from the design concept to the materials being used, the bolts, the square nuts and the way the bottle cage is installed to the Part B. Shouldnt it be threaded so that the requirement for the square nuts not be used at all?
Perhaps a quick release version should be come to mind?
I do believe however, it is something nice to have, not a need but more than a want.
Have fun riding your awesome bikes fellow cyclist!

Rated 5 out of 5 by plasticblackspecs simple and stylish
excellent product. clean simple design. able to have the option of one or two bottle holders. the ability to have a tilt angle gave the option of just upright or "aerodynamic" sleek look. I recommended it to all my friends and now 4 guys are using it. hahaha. Make sure your bottle cage holder goes around the bottle though (as opposed to the exposed type) otherwise every time you hit a bump, the bottle will drop out.
Elite Ciussi Inox Cage / Tacx Uni Bottle Cage / Elite Sior Fibreglass Bottle Cage - Yes
Clarks Polycarbonate Bottle Cage / SKS Topcage Bottle Cage / Topeak Shuttle CB Carbon Bottle Cage - No.
One extra. It works as a pretty decent rear "mudguard" the bottle actually prevents your butt from getting wet. Found out when I was riding on wet roads and I forgot to bring my rear fenders out. Surprisingly, dry rear :) FTW!

Rated 3 out of 5 by Anonymous It works but it's fiddly
Recently acquired and fitted, it works just fine - I fitted it to a FS MTB and the bike's rear guard keeps the bottle nice and clean, but if you haven't got a rear guard, make sure you have a bottle with a cap!
Why did I need this item? - the muppet that designed my bike's frame ensured a standard bottle fouls the rear shock!
Downsides....instructions a bit spa**e, I'd really recommend that you remove the saddle - it makes fitting the clamp soooo much easier. You also might want to fit any bottle cage **before** you connect the cage holder to the bit that clamps to the saddle. Captive nuts supplied for this but no bolts - and it's a fiddly job!
