I have used this cage for ~150 miles and I can tell you that this cage is perfect! I cannot find any fault, it is very durable, low profile, and it looks good! I have a specialized bottle and it works perfectly with this cage. Aside from the product itself, the customer service is amazing! I am a beginner cyclist and I stupidly wore jeans while biking (without a leg strap) and it caught on the cage and obviously, broke. There was no fault with the durability, it was completely my fault. However, I contacted customer service to see if I could get a replacement. They sent a replacement for free and it arrived within a week! The replacement was the same cage, and the whole process was seamless! I have bought all my accessories from specialized because you can't beat the value, the product, or the service!
