The Arundel Dave-O established a new template for carbon bottle cages when it launched in 2001. Before the Dave-O, carbon cages followed traditional wire frame shapes with predictable results. Arundel rethought the geometry entirely, using wider arms with more surface contact and a curved profile that wraps around the bottle without relying on extreme tension to hold it in place. The design has been copied repeatedly since then, but the original execution remains the reference point.

Carbon fiber construction keeps the weight at 30 grams while maintaining the stiffness needed to prevent the cage from flexing when you're jamming a bottle back in mid-ride. The layup uses either a 3K weave or UD (unidirectional) carbon depending on the version, both of which provide the structural integrity to handle bottles being inserted and removed thousands of times without the cage loosening up or developing stress cracks at the mounting points.

The wider arm design means bottles release more easily compared to cages that rely on tighter grip. If you've used cages where you have to yank hard to get the bottle out, especially on bumpy descents when you need hydration quickly, the difference is immediately obvious. The Dave-O holds bottles securely enough that you won't lose one on rough roads, but extraction happens with a smooth pull rather than a wrestling match. This becomes relevant on long rides when you're reaching for your bottle repeatedly and don't want to think about it.... Read More
