The Arundel Mandible is a high-grip bottle cage designed for cyclists who need dependable bottle retention on demanding terrain. Built from carbon fiber, it weighs just 28 grams while providing exceptional stiffness and holding power. The cage’s three-dimensional geometry features flared edges at the top for smooth bottle insertion and rounded arm sections that prevent snagging when removing bottles mid-ride. It includes two sets of mounting holes spaced 20mm apart, giving you vertical adjustment flexibility for frame clearance or positioning with multiple bottles. Proven in professional racing—Grand Tours, Spring Classics, and World Championships—the Mandible holds bottles firmly through rough gravel descents and high-speed pavement without rattle or ejection. Compatible with standard 73-74mm diameter bottles and mounts to down tube positions. Best suited for road, gravel, and mountain bike riders prioritizing lightweight construction without compromising security.
