I would by this product again
I always had a problem using a 75oml bottle with an ordinary bottle cage. The side loading feature with this item solved all of my problems.

Never lose a bottle again!
I used this on my Checkpoint to get three full sized bottles inside my main triangle as well as my other bikes and they work awesome. Completed DK200, LandRun, Barry Roubaix and Lutsen99 without having to think twice about losing a bottle. Just be sure you get the right combination of Left and Right load cages so you grab from the same side!
