bottle is secure and not worried about losing the bottle on some fun downhill.
I really like it
The lock system works great. I ride on the east coast rocks and have not lost a bottle yet, and I have tried. Drinking from the 600 bottle has a little learning curve. The bottle is a little stiff and the nozzle sucks shut if you drink from it like a normal bottle. With a little practice I have learned to drink from it and have no problems. This is the only bottle system I could find that fits on a Ibis Ripmo and, yes it fits with 1/8" to spare.
Very easy to set up
I love the concept. I'm using these on a Tarmac SL7 and love the clean look it has without actual cages. The magnets are strong and keep the bottle tight on the frame. The 600ml bottle is a little smaller than I thought it would be, but not a bad size for a seat tube bottle. The bottle is stiff and not very squeezable. The cap/top of this is atrocious. The squirt nozzle will not stay open for the liquid to exit due to the vacuum. Since the bottle is so stiff you cant really squeeze it to squirt out the liquid. Also, when it does work the liquid comes out around the outside of the nozzle causing the liquid to go all over you. I did buy the 800ml bottle with the new top and it works great. The 800 ml bottle is more squeezable and the top works great. I would not buy this 600ml bottle again.
