I was hesitant to buy these cages as they are expensive, and I was not too familiar with the brand, but they were a perfect match for my bike, so I went for it.
These cages are light, very strong, and better looking in person. I've never lost a bottle yet. Well that's not true. I was hit from behind, by a car going 50mph. My bike was toast, but the cages weren't, and that was the only time I lost the bottles.
I got suckered in by the good looks - I wanted something that would look really sharp on my new bike. This definitely fits that mark. Looks great, works perfectly. Bottle cages aren't rocket science, so it was hard to justify the cost, but ultimately am happy with the choice.
