Arundel built its name on carbon cages — the Mandible and Dave-O have been winning Grand Tours and Classics for over two decades, and that's still the brand's center of gravity. The C30G is the cage you buy when you want that Arundel DNA on a bike that doesn't need a $80 cage on it. Think second bike, gravel rig, commuter, trainer setup, or any frame where you want bottle retention you can trust without spending Mandible money.

The construction is a carbon-infused composite — not full carbon weave, but reinforced enough to deliver the snappy, responsive arm feel that makes a good cage hold a bottle through cobbles and washboard. Arundel positions this one between their nylon-reinforced Sport cage and the full-carbon offerings, and at 38 grams it's closer to the carbon end of the scale than the plastic end. For reference, the Sport sits in the mid-50-gram range and the Mandible UD is in the 28-gram neighborhood, so the C30G splits the difference on weight while landing well under the price of either carbon option.

Where this cage earns its keep is the bottle grip. Arundel's arm geometry is the part of the recipe they've been refining since 2000, and the C30G uses the same general approach — arms shaped to apply consistent retention pressure across the bottle's circumference rather than pinching at a single point. The result is a cage that holds securely on rough pavement and trail surfaces without fighting you when you reach down for a drink at speed.... Read More
