Here's an update on the IRD carbon cages that I have been using for over a year now (previous thread 12/22/03). All is well in water bottle land. Not a hint of ejection or wobbling. The cages hold the bottles secure. I use a 28oz and 22oz bottles. Living in New Hampshaaaah, the back roads can be quite treacherous. I have been behind riders whose bottles do a good impersonation of the space shuttle lifting off, and my bottles are held firm. Be advised; these cages are thin and flexible. If u are one who rips out the bottle and jams it back into the cage, these may not be for u. Check them out; glorycycles/waterbottles.html. If this doesn't take u right to the link, click on 'tools and accessories', then 'water bottles'. Fish
