Bike Water Bottle Holder Ultralight Bottle Cages with Screws Tool

On a seat post mount, you need to tie the cage together to keep it from expanding too much. This is especially important if you’re using an extra large/long water bottle. The material is just a bit too springy. But if you do tie it, it works really well. Very impressive engineering. Not overly strong/heavy or hard to use, but not overly weak. Goldilocks zone. Importantly, it keeps the bottle from slipping out the bottom (unlike most cages out there)

This is a great bottle holder. It was very easy to install and stays in place during the rides. Fits a variety of sizes, seems durable so far.

Bit of a tight fit for what I consider normal width water bottles. But does work. Kool look ! Haven’t lost a bottle yet doing some pretty rocky mountain bike riding.

I bought these ROCKBROS Bike Water Bottle Holders after a frustrating experience with a different brand. I picked up two similar cages at my local bike shop, and one of them actually broke on the very first ride — it just snapped under normal use. These ROCKBROS cages are in a completely different league. They feel much sturdier and more solid right out of the box. The material seems high-quality and they appear practically indestructible compared to the ones that failed on me. I’ve been using them regularly now and they hold my bottles securely, even on rougher rides, with zero flex or worry. Installation was easy with the included screws and tool, and the ultra-light design is a nice bonus without sacrificing any strength. They look clean on my bike too. If you’ve had bad luck with flimsy bottle cages like I did, do yourself a favor and get these ROCKBROS ones. Excellent value and real peace of mind. Highly recommended!

Looks very "cheap" and that it would break easily. I have used it for awhile now and it appears to have held up well. More durable than it looked!

Nice to have this kind of water holder you can flip it upside down and it holds water bottles

--Think carefully if you want to risk permanent damage to your bikes only water bottle mount point. Mounting the cage was extremely tricky because of the location. It was tight and impossible to start the bolt with your fingers-you had to try and start it on the end of an allen wrench, which anyone with experience knows is a no-no. The fact that it so nearly fit -you could catch the first thread but only with the bolt at an angle- might cause frustration and the temptation to press on with just a little more pressure, a few more turns. If you do, you will cross-thread the bolt and could cause permanent damage. To repair it you would then be forced to try something like drilling it out and installing a 'riv-nut' -which would also be very difficult without a small right-angle drill and short drill bit and special installation tool for the 'riv-nut'-or you'd need to remove the rear tire and fender and.......!!! Kiss your soon to be frustrating afternoon or $$$ goodbye! To fix the cages I needed to use a 'rat tail' file to effectively lengthen the distance between the mounting slots on the water bottle holder. What should have been literally a 2 minute install for a 10 year old turned into a frustrating 30 minutes. Just FYI- it was definitely the cages cause I tried both from my order and both were too short. Both a 'no-go' on an Aventon and an old Schwinn as well -But much more accessible. After mods it took less than 2 minutes.... to do both...with loctite!! -you get the picture. The cages already use extended slots for mounting flexibility. I don't see that an extra 0.5 mm in slot length is going to alter the engineering. And it wasn't just plastic 'flash' from a seam line that could be easily removed with a small hobby razor, or even a small steak knife. It took 10 minutes on each with the file, or you might be ok carefully using a Dremel tool. (I've always found the Dremel allows you to make a bad situation worse, much more quickly.) I am seriously questioning my purchase, just to save a couple $$- It's not worth the time and frustration. It would be sooo easy for a new mechanic/rider (or an experienced one in a hurry) to cross-thread the hole and ruin the only water bottle mount.... I've used other ROCKBROS parts on my bikes and have always found them to be decent quality for the price. I just installed one of their bags on the rear rack of that same Lectric and the "Warranty Card" actually said that they would offer replacement within 15 DAYS of purchase or "free maintenance" within 30 DAYS of purchase. Everything else is in Chinese so I'm not sure if I'm required to mail the item back to them in China and I suspect that even the international phone call to find out would be much more $$ than the item was worth..... I can't help but think of the cosmic divide between ROCKBROS "Warranty" and what Lectric just did to fix the brake issue on the XP 3.0 Customer service wise I think that tells me everything I really need to know. Consider spending the couple extra $$ on your water bottle cages.........And DON"T CROSS-THREAD THE DARN THING!! -Hope this helps

easy to install, use with ROCKBROS water bottle

even though it is a Ultra light weight bottle cage, it is easily breakable and not of good quality

Font le travail. Fonctionnent avec toutes les bouteilles et bidons.

Solid structure and holds bottle well, no shaking....

Atende a expectativa.

I thought it would be finicky ,however it is sturdy, the screws are great and it looks awesome
