Triseven Bottle Holder Bike - Drink Holder Bike - for 2 Water Bottles and 2 CO2 Cartridges - Bike Cup Holder for Drink Bottle - Fit Bicycles - Bicycle Accessories - without Water Bottles

I bought this double bottle holder for my wife, and she likes it very much. It's easy to install, nice color and good quality product. Very stable, it fits perfect and holds bottles very good. Easy to use during ride.

Fits like a charm on my Argon E118. Unbelievably sturdy! The quality, installation are an A+ IMO.

The first product arrived without the holes milled correctly -- so it was impossible to attach a bottle cage. I chose the option of a replacement. That came with an extra set of screws (you only need one set) and the brackets to attach the item to the saddle missing. My advice, skip this manufacturer and go for a better product.

The design is about 90% good. The positioning is good and well thought out. All the bolt holes are extremely easy to strip while installing. The bolt holes that hold the device to the seat and the bolt holes to attach bottle cases. Not a big deal because I went and picked up some m5 nylock nuts and made double sure nothing comes loose. Having said that they could have engineered it to not be threaded and to have nuts.

worked like a charm in my canyon endurance bike. A bit hard to put on but once it's in it's great.

My wife needed the extra capacity as she started training for Ironman distances.It’s not aircraft grade aluminum. It’s soft. After 100 miles on the road, the vibrations and the weight of the water bottles cantilevered out on the end caused the bracket to flex and allow the screws to loosen. Using blue loctite paste on the screws didn’t seem to completely prevent it. I even had one screw strip the threads in the bracket. Went to Lowe’s and picked up a set of M5 nyloc nuts and flat washers to keep the screws tight and clamped. It’s a little awkward to get under the seat to get them on, but doable.The bracket was slightly crooked. Even though it was attached straight on the seat rails, the bottles sat a little to the left. With a little muscle, it straighten up and centered over the rear tire.Otherwise the option to attach 1 or 2 bottle cages works out nicely. I fashioned a custom bracket for a tail light in the center “single” config position. It sits between the two bottles and still visible.When buying cages, make sure you get ones that are robust enough to hold onto your bottle even when riding over rough patches and the occasion pothole. I went with the XLab Gorilla 10lb cages.

perfet fit for my bike and holds the bottle even on a bumpy road

My single speed track bike has no bottle mounts, and I’ve been looking for one of these for a while. Came with all the peices for the mounting bracket and with 1 bottle holder. It was a bit tricky to get the bar clamps in place as you cannot tighten the Allen screw after it is wedged up under the seat. It screwed on tight and seems sturdy enough to take a lifetime of abuse. Came with a little blue dot of Teflon on the screws so they won’t fall out, a nice touch. I swapped out the bottle cage for a white one to match my bike. Will probably add a second for longer rides. There are two mounting positions, I mounted it in the lower angle to keep the bottles from hitting my butt when I ride upright without using the bars.Update: after using this bottle mount for over a year I an still happy with it. I found out that bottles mounted under the saddle are called butt rockets cuz they fly out if you hit too many bumps. I got the Boa FidLock magnetic bottle holder to solve that problem. Now it’s perfect.
