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

There are two angle options straight and a bit tilted. I choose the straight bottle option and it works wonderfully. Love that it can hold two CO2s. There’s also a nice size gap between the saddle and the bottle cages that you can fit a tube easily if you don’t have other storage options. When I didn’t have a storage option I strapped the tube in that gap with Velcro straps. It held for 100+ miles without falling. Highly recommend this.

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.

The good thing about this cage holder is there are 2 positions that it can be installed. On the horizontal position, you could likely hit your bottle when you swing your leg over to ride unless you use a short bottle. The other position, at an angle, keeps the bottle below the saddle's height, but for short guy like me the bottle comes down close to the back wheel. You can also chose to mount 2 bottle cages or only 1. Other convenient features including mounting 2 CO2 catridges, and probably a small took bag. The cage mount is made of aluminum, lightweight and look nice on the bike. I have not perfected the art of pulling the back saddle bottle out to drink on mid ride, so can't comment on it. With the appropriate cages, you wouldn't have to worry about losing bottles from this set up.

I used it for an IM 70.3 event in Florida, and installing it was a headache. The bolts didn’t fit properly, so I had to use straps to secure it, and even then, it wasn’t fully stable. I lost a bottle during the bike course and had to adjust my hydration strategy.

Easy to install, seems like good quality material - super simple design. I just put one bottle cage on for now, I like that you have the option for centered single bottle or dual bottle cages. Also happy to see I can mount my tube repair kit underneath without difficulty still. Didn’t have to move the seat to make it fit so that was also a big plus. I’ll update review with how it rides over time.

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.

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.

My husband love his holder. I was weary about buying this because I thought it was gonna get in the way when he was sitting down, but after some adjustments, it was perfect and he was able to grab it really easily.

Content du produit je suis triathlète et de plus je vais pouvoir l'utiliser en course et pour des entraînement longue distance travailler le foncier sinon très utile facile à mettre en place et peu encombrant bon produit.....

Se sujeta bien y es ligero, cumple

The cage holder came as described. It was easy to install on my ISM saddle. The bottles sit in an accessible position. The screw in CO2 cannister holes are a great add on, and also provide some leverage to attach a tube, and tire levers to the cage holder in front of the bottles.

Il supporto è comodo e robusto. sostiene bene il peso. L'installazione non è delle più comode. Il sistema di montaggio è intuitivo, ma può risultare un po' scomodo in base al tipo di sella al quale si vuole agganciare. Bisogna fare attenzione: per evitare di perdere le borracce dovute alla vibrazioni, quando si prendono buche o sconnesso, si deve fare attenzione a quale "portaborraccia" si monta! La borraccia deve entrare ad "incastro", quelle solo inserite a pressione è facile perderle. Possibile montare 2 slot "portaborraccia" - portaoggetti. Un buon prodotto,

sehr gute Ergänzung bei meinem ORBEA Ordu Tri-Bike. Nach der Verschiebung des Sattels auf der Befestigung ganz nach vorne, war eine Halterung notwendig. Der Tri-Seven Triathlon Sattel passt super.
