These are classic looking bottle cages. They are lightweight. Removing and insert a bottle is easy. I recently had one bottle fly out but I was doing 35mph on very rough pavement.
Otherwise they've held on to bottles on really rough gravel rides. The paint on the cage does rub off onto my bottles. This is a problem i had with other aluminum cages as well. Overall it's a good cage from the money.
Best value of any cage I've used. I have tried many other cheap options (can't justify spending more than $10 on a fancy carbon or titanium cage, myself) and none are as reliable as this one. Should last you a long while. And a few color options to boot! What's not to like?
This bottle cage is very light and I found nothing wrong with it. If you want to waste your money you can spend a lot more on gimmick bottle holders and get nothing better in performance. Put your money into high quality tires or high performance wheels and don't waste it on expensive, fancy looking bottle holders that offer nothing more than this product.
