I thought about getting King Ti Cages for my Lynskey because I like their stainless ones I have on another bike but at $60 a pop it made no sense to me just to have a 28 gram cage. If your deadset on those Kings, Bike Bling had the lowest cost I could find, see: King Titanium Water Bottle Cage from Bike Bling.

There is also a couple of less expensive TI cages that you may or may not like, such as this Blackburn; see: Blackburn Swerve Titanium Bottle Cage from BikeBling.com this one weighs 26 grms which is lighter than the King; and then theres this one which is the lightest of the TI cages plus cost less than the other two; see: wiggle.com | LifeLine Titanium Bottle Cage | Bottle Cages

Anyway I thought I would show you some options.
