• Sturdy frame of metal shines,
• Holds my drink with gentle grace.
• On my bike, it rides so well,
• Clasps the bottle, all day through,
• Tanaka cage, my trusty friend.

Wow, not a great poem, but it's what you are getting!  

Lightweight stainless bottle cages.  Analog has these custom cerakoted in a few fun colors.  Made in Japan.  Good for town and road bikes, touring bikes.  Get the by Tanaka for rough stuff riding.
