Blackburn Camber UD Matte Carbon Fiber 30g bottle cage. Blackburn designed the Camber Carbon bottle cage with features to make it stand out from the competition. It has a flared mouth to improve ease of bottle insertion. Unique reinforcing side ribs increase stiffness to boost strength and bottle grip. The lower cradle/bottle stop area is designed to provide more support for critical strength in an area where other carbon cages fail. The Blackburn Camber Carbon Cage is both light and strong - strong enough that it's backed by Blackburn's Lifetime Warranty. If you have any questions don't hesitate to ask.
