I'm probably 200 miles into these cages so far since installing. I've been on some pretty rough terrain and they're solid. I've got them holding two Cambelbak Podium bottles and there isn't any noise that I can perceive. The cages definitely stretch and wrap around whichever bottle I insert. I get the sense that they'll be reliable for the foreseeable future.
Even with elite brand bottles I have issues. Lost 3 in one race.
the rubber tip comes off
As expected. Tough to keep white clean.
Bottle cage allows for easy grabbing of water bottles. Expands some for larger sports drink bottles.
Very nice modern look and highly functional. Seem like they will last for a very long time and hold the water bottles nice and snug.
