Wolf Tooth B-RAD Mounting Bases

Wolf Tooth B-RAD Mounting Bases are the foundation of the B-RAD™ (Bottle Relocation & Accessory Device) system, giving riders a flexible way to optimize on-bike storage. Whether you're making room for a frame bag, clearing a rear shock, or adding extra bottles for long days in the saddle, these bases allow you to reposition and expand your mounting options using your existing bottle cage bosses. Machined from durable 6061-T6 aluminum, B-RAD Mounting Bases are lightweight, rust-proof, and built to handle demanding trail, gravel, and bikepacking use. By creating a modular mounting platform, they allow you to customize bottle placement or attach compatible B-RAD accessories for tools, bags, and other ride essentials.
