Bottle holders look the part on my bike, there are two included and they hold two bottles, so does exactly what you would expect.......However the issue arises when you come to fit them to your bike. You only get two long blots with these, so half the amount of bolts you need to actually attach two bottle cages to your bike. The bolts are too long if you are fitting them to your frame and here's the kicker, I assumed they would be longer enough to use on the twin cage bracket but they are too short, as they will go through one cage, the bracket but not out the other side to make contact with the second cage. End result is you either have to buy extra bolts, or you end up with one cage attached from the top and the second attached from the bottom which isn't a secure fit for when you are reaching back for your bottles as you ride as they move. Great product let down by a basic error that I am amazed was never noticed by the company especially when they sell the bracket and twin cages as a pack. I would recommend the product just be aware that you don't get everything you need to actually use them.
Good thank you
