B-RAD Mounting Bases


B-RAD (Be-Rad), Bottle Relocation and Accessory Device, is an innovative and extremely flexible system for organizing on-bike bottle and accessory storage using bottle cage mounts.  The system is inclusive of 3 different mounting bases, the B-RAD 2-4, and growing number of mountable accessories.

This product page is for the mounting bases.  The rest of the B-RAD system accesories mount to these bases.  See compatibility section below for dimensions

  • B-RAD 2
    • This 2 slot base with 2 threaded mounting holes is the shortest base designed for moving a bottle around to an optimal location on a smaller or dual suspension frames or to mount B-RAD accessories to on an unused set of bottle cage mounts.  
  • B-RAD 3
    • This 3 slot base with 4 threaded holes provide additional adjustment and mounting options vs the B-RAD 2.  A very typical application would be to mount a bottle cage in the forward threaded holes with a B-RAD accessory tucked behind it. Addtionally, this mounts perfectly to triple bottle mounts on frames and forks. The B-RAD 3 includes zip ties, channels for the zip ties, and closed cell neoprene foam pad for secure mounting. 
  • B-RAD 4
    • This 4 slot base is the longest base with 9 threaded holes for the ultimate flexibility and capacity when bike packing, touring, communting or just exploring on 2 wheels.  It is long enough to mount 2 smaller bottles inline or multiple accessories. The B-RAD 4 includes zip ties, channels for the zip ties, and closed cell neoprene foam pad for secure mounting.
