I've had this water bottle cage for about a year and it was worked flawlessly so far. I use it with a 24oz insulated Polar water bottle and it fits securely in the cage while still sliding out easily enough to grab one handed. I have never had my water bottle fall out of the cage.The black finish has held up fine. The water bottle cage also came with two new bolts to attach it to the standard brackets on my bike frame. This was highly appreciated since the bolts that had been in my frame were pretty rusty/grungy looking.There may be lighter wattle bottle cages, but it's not like the thing is super heavy. I ride at most 30 miles at a time, so I'm a pretty causal rider, so things like weight don't really matter to me. For commuters or casual weekend riding, this water bottle holder fulfills its purpose just fine.It's a simple alloy bottle cage said and done. Not a whole lot to it but that's just how I like it. Thicker diameter than most cages so that's a plus. It's got a nice gloss finish which I like, not a big fan of flat colors. Not much to say really. Of course if you do some hard riding it'll probably break at the weld, but that's a simple alloy cage for you. I put more abuse on these types of cages than anyone probably should and they usually last me anywhere between 6 months to a year. For the price that's honestly nothing to complain about and I've always considered these types of bottle cages a disposable item. For road, xc, light trail riding, commuting, or anything of that sort you'll probably never have a problem. Great product at a great value, it is what it is.It's difficult to write a review like this, because someone is going to complain that I'm not reviewing the item in this ad., and instead complaining about receiving the wrong item, but let me explain.I searched for a long time, trying to find the item pictured in this ad., because my favorite water bottle is designed to engage the large round section in front of the item pictured in their ad.. Instead I got a water bottle holder like most of the newer designs, where the front portion has been run through a set of rollers in order flatten that section, so that a water bottle can slide smoothly up and down. I don't want that, I want the one in their picture, the one I thought I was getting, so I think this review is a fair warning, you will not be getting the bottle holder in their picture, you will be getting the newer design.It's very very close, and I'm sure most people would say "big deal, or the newer design is better", but it is a big deal, and the newer design is not better. Bottom line is, you will not be getting the item shown in their picture.Addendum: lol ... after posting this review, I went back and read all the other negative reviews, which I should have done before, but the fact is, dozens of other people said the exact same thing ... you do not get the item shown in their picture, you get the item shown in mine (see attached photo).There's a lady at our church who rides a bicycle to get around. Someone had given her the bike, and it was in need of several things to make it safe and legal. I got this water bottle holder for her, and it came well packaged and in good shape. Personally when I ride, I use a camelback, but as the saying goes, you can't carry too much water, so a water bottle holder is always good. I haven't checked back with this lady to see how it's working, but as a former bike mechanic, I can tell you they looked like it was fine and would work well.To fit standard water bottles. I don't use a reusable water bottle because the water in my city sucks so I stick to regular sized water bottles. I had to clamp down on it to secure the regular plastic capped bottles.. i guess i didn't have to use my muscles i could have simply stepped on it for the desired diameter. Feels secure and snug and it was cheaper here than my local bike shop, which wanted to charge me 8 for it, 10 to install... wtf this is the easiest thing to install.. get it and stay hydrated!This bicycle water bottle cage is your typical or generic cage that is sold in every bike shop and retail store. It is composed of all metal, which means it is built tough. While it can hold many sizes of bottles you must use your strength to bend the cage to make it tighter or looser. I tried a Dasani water bottle and it fit but I have to bend the cage so much I was afraid it would damage it. Also take note, that if you ride a smaller frame bicycle (such as 16'') this cage may be too large for your bike. Sure the cage may fit but there is no room to put a bottle in it once it's installed. Instead of spending a few dollars for this generic cage I would suggest I am rebuilding a bike for my son and the bottle holder was shot. I bought the Trek frame at a garage sale for $5. It was originally a bike that retailed for over $500 so I figured I could spend a little to replace damaged components.This Alloy Water bottle cage looks great and works well. It is nothing special but it is so much nicer than the one that was falling apart and my son is stoked that his bike will still have a bottle holder.I actually bought two frames for $10 total so have one more to go. Now that I have finished the first build I will be buying another one of these for the second build.Don't forget the screws, they were not included.
