Pair (2) Zipp vuka bta black carbon fiber water bottle cages. Used. Very good condition, no damage, these will last forever and not bend or loose their strength unless you break them! These weigh nothing! Ok, they exist, so they have mass and must weigh something, but they feel like they weigh nothing! Shipping to the lower 48 US States only. All questions and requests for additional info or photos will be answered quickly.
