Bases are the foundation for the B-RAD system and the rest of the B-RAD system mounts to them

  • Reposition bottle cages using existing bottle cage mounts on your bike

  • Lightweight, durable, rust-proof materials

  • Customize storage to your specific needs with flexible B-RAD system

  • The 2-Slot Base can move a bottle or other accessory to an optimal location even on a smaller or dual suspension frame
  • B-RAD 2 base instructions
  • The 3 slot base with 4 threaded holes provides additional adjustment and mounting options vs the B-RAD 2. A typical application would be to mount a bottle cage in the forward threaded holes with a B-RAD accessory tucked behind it. This mounts perfectly to triple bottle mounts on frames and forks. The B-RAD 3 includes a recommended zip tie, channels for the zip tie, and a foam pad for secure mounting
  • B-RAD 3 base instructions
  • The 4 slot base is the longest base with 9 threaded holes for the ultimate flexibility and capacity when bike packing, touring, commuting or just exploring on 2 wheels. It′s long enough to mount 2 small bottles inline or multiple accessories. The B-RAD 4 includes the required zip ties, channels for the zip ties, and a foam pad for secure mounting
  • B-RAD 4 base instructions
    • The Dogbone can be used to offset a bottle or other accessory to an optimal location. Most commonly used for smaller, curved, or dual suspension frames
    • Dogbone base instructions



      • Mounting any of the bases requires the use of at least 2 standard threaded bottle cage mounts. B-RAD 3 and 4 should use the auxiliary foam pad (to protect your frame) and zip tie to secure the base. Any other mounting methods are not recommended
      • You may need a Problem Solvers Space Out Kit or similar method to clear the front derailleur clamp. Be sure to use bolts with additional length equivalent to the extra spacing added
      • Compatible with any frame that uses standard 64mm spacing bottle cage braze-ons (basically every modern frame)
      • Hardware included is T25 Torx head
